*NOTE: THE TERM EARTH USED THROUGHOUT THIS GUIDE IS THE DIRECT EQUIVALENT OF THE NORTH AMERICAN TERM GROUND.
3.2 Labels
See Safety Guide (SFTY/4L M/G11) for equipment labelling information.
4. INSTALLING, COMMISSIONING AND SERVICING
Equipment connections
Personnel undertaking installation, commissioning or servicing work for this equipment should be aware of the correct working procedures to ensure safety.
The equipment documentation should be consulted before installing, commissioning, or servicing the equipment.
Terminals exposed during installation, commissioning and maintenance may present a hazardous voltage unless the equipment is electrically isolated.
The clamping screws of all terminal block connectors, for field wiring, using M4 screws shall be tightened to a nominal torque of 1.3 Nm.
Equipment intended for rack or panel mounting is for use on a flat surface of a Type 1 enclosure, as defined by Underwriters Laboratories (UL).
Any disassembly of the equipment may expose parts at hazardous voltage, also electronic parts may be damaged if suitable electrostatic voltage discharge (ESD) precautions are not taken.
If there is unlocked access to the rear of the equipment, care should be taken by all personnel to avoid electric shock or energy hazards.
Voltage and current connections shall be made using insulated crimp terminations to ensure that terminal block insulation requirements are maintained for safety.
Watchdog (self-monitoring) contacts are provided in numerical relays to indicate the health of the device. Schneider Electric strongly recommends that these contacts are hardwired into the substation's automation system, for alarm purposes.
Pxxx/EN SS/G11 Safety Section Page 5/8
To ensure that wires are correctly terminated the correct crimp terminal and tool for the wire size should be used.
The equipment must be connected in accordance with the appropriate connection diagram.
Protection Class I Equipment
- Before energizing the equipment it must be earthed using the protective conductor terminal, if provided, or the appropriate termination of the supply plug in the case of plug connected equipment.
- The protective conductor (earth) connection must not be removed since the protection against electric shock provided by the equipment would be lost.
- When the protective (earth) conductor terminal (PCT) is also used to terminate cable screens, etc., it is essential that the integrity of the protective (earth) conductor is checked after the addition or removal of such functional earth connections. For M4 stud PCTs the integrity of the protective (earth) connections should be ensured by use of a locknut or similar.
The recommended minimum protective conductor (earth) wire size is 2.5 mm² (3.3 mm² for North America) unless otherwise stated in the technical data section of the equipment documentation, or otherwise required by local or country wiring regulations.
The protective conductor (earth) connection must be low-inductance and as short as possible.
All connections to the equipment must have a defined potential. Connections that are pre-wired, but not used, should preferably be grounded when binary inputs and output relays are isolated. When binary inputs and output relays are connected to common potential, the pre-wired but unused connections should be connected to the common potential of the grouped connections.
Before energizing the equipment, the following should be checked:
- Voltage rating/polarity (rating label/equipment documentation),
- CT circuit rating (rating label) and integrity of connections,
- Protective fuse rating,
- Integrity of the protective conductor (earth) connection (where applicable),
- Voltage and current rating of external wiring, applicable to the application.
Accidental touching of exposed terminals
If working in an area of restricted space, such as a cubicle, where there is a risk of electric shock due to accidental touching of terminals which do not comply with IP20 rating, then a suitable protective barrier should be provided.
Equipment use
If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
Removal of the equipment front panel/cover
Removal of the equipment front panel/cover may expose hazardous live parts, which must not be touched until the electrical power is removed.
Pxxx/EN SS/G11 Page 6/8 Safety Section
UL and CSA/CUL Listed or Recognized equipment
To maintain UL and CSA/CUL Listing/Recognized status for North America the equipment should be installed using UL or CSA Listed or Recognized parts for the following items: connection cables, protective fuses/fuseholders or circuit breakers, insulation crimp terminals and replacement internal battery, as specified in the equipment documentation.
For external protective fuses a UL or CSA Listed fuse shall be used. The Listed type shall be a Class J time delay fuse, with a maximum current rating of 15 A and a minimum d.c. rating of 250 Vd.c., for example type AJT15.
Where UL or CSA Listing of the equipment is not required, a high rupture capacity (HRC) fuse type with a maximum current rating of 16 Amps and a minimum d.c. rating of 250 Vd.c. may be used, for example Red Spot type NIT or TIA.
Equipment operating conditions
The equipment should be operated within the specified electrical and environmental limits.
Current transformer circuits
Do not open the secondary circuit of a live CT since the high voltage produced may be lethal to personnel and could damage insulation. Generally, for safety, the secondary of the line CT must be shorted before opening any connections to it.
For most equipment with ring-terminal connections, the threaded terminal block for current transformer termination has automatic CT shorting on removal of the module. Therefore external shorting of the CTs may not be required, the equipment documentation should be checked to see if this applies.
For equipment with pin-terminal connections, the threaded terminal block for current transformer termination does NOT have automatic CT shorting on removal of the module.
External resistors, including voltage dependent resistors (VDRs)
Where external resistors, including voltage dependent resistors (VDRs), are fitted to the equipment, these may present a risk of electric shock or burns, if touched.
Battery replacement
Where internal batteries are fitted they should be replaced with the recommended type and be installed with the correct polarity to avoid possible damage to the equipment, buildings and persons.
Insulation and dielectric strength testing
Insulation testing may leave capacitors charged up to a hazardous voltage. At the end of each part of the test, the voltage should be gradually reduced to zero, to discharge capacitors, before the test leads are disconnected.
Insertion of modules and pcb cards
Modules and PCB cards must not be inserted into or withdrawn from the equipment whilst it is energized, since this may result in damage.
Insertion and withdrawal of extender cards
Extender cards are available for some equipment. If an extender card is used, this should not be inserted or withdrawn from the equipment whilst it is energized. This is to avoid possible shock or damage hazards. Hazardous live voltages may be accessible on the extender card.
Pxxx/EN SS/G11 Safety Section Page 7/8
External test blocks and test plugs
Great care should be taken when using external test blocks and test plugs such as the MMLG, MMLB and MiCOM P990 types, hazardous voltages may be accessible when using these. *CT shorting links must be in place before the insertion or removal of MMLB test plugs, to avoid potentially lethal voltages.
*Note: When a MiCOM P992 Test Plug is inserted into the MiCOM P991 Test Block, the secondaries of the line CTs are automatically shorted, making them safe.
Fiber optic communication
Where fiber optic communication devices are fitted, these should not be viewed directly. Optical power meters should be used to determine the operation or signal level of the device.
Cleaning
The equipment may be cleaned using a lint free cloth dampened with clean water, when no connections are energized. Contact fingers of test plugs are normally protected by petroleum jelly, which should not be removed.
5. DECOMMISSIONING AND DISPOSAL
De-commissioning The supply input (auxiliary) for the equipment may include capacitors across the supply or to earth. To avoid electric shock or energy hazards, after completely isolating the supplies to the equipment (both poles of any dc supply), the capacitors should be safely discharged via the external terminals prior to de-commissioning.
Disposal
It is recommended that incineration and disposal to water courses is avoided. The equipment should be disposed of in a safe manner. Any equipment containing batteries should have them removed before disposal, taking precautions to avoid short circuits. Particular regulations within the country of operation, may apply to the disposal of the equipment.
Pxxx/EN SS/G11 Page 8/8 Safety Section
6. TECHNICAL SPECIFICATIONS FOR SAFETY Unless otherwise stated in the equipment technical manual, the following data is applicable.
6.1 Protective fuse rating The recommended maximum rating of the external protective fuse for equipments is 16A, high rupture capacity (HRC) Red Spot type NIT, or TIA, or equivalent. Unless otherwise stated in equipment technical manual, the following data is applicable. The protective fuse should be located as close to the unit as possible.
CAUTION - CTs must NOT be fused since open circuiting them may produce lethal hazardous voltages.

3. INTRODUCTION TO THE MiCOM P921, P922 & P923 RELAYS The range of MiCOM protection relays is built on the success of the MIDOS, K and MODN ranges by incorporating the last changes in numerical technology. Relays from the MiCOM P92x range are fully compatible and use the same modular box concept.
MiCOM P921, P922 and P923 relays provide comprehensive voltage and frequency protection.
In addition to its protective functions, each relay offers control and recording features. They can be fully integrated to a control system so protection, control, data acquisition and recording of faults, events and disturbances can be made available.
The relays are equipped on the front panel with a liquid crystal display (LCD) with 2 x 16 back-lit alphanumerical characters, a tactile 7 button keypad (to access all settings, clear alarms and read measurements) and 8 LEDs that indicate the status of MiCOM P921, P922 and P923 relays.
In addition, the use of the RS485 communication port makes it possible to read, reinitialise and change the settings of the relays, if required, from a local or remote PC computer loaded with MiCOM S1 software.
Its flexibility of use, reduced maintenance requirements and ease of integration allow the MiCOM P92x range to provide an adaptable solution for the problems of the protection of electric networks.

1. GENERAL CONSIDERATIONS
1.1 Receipt of relays
Protective relays, although generally of robust construction, require careful treatment prior to installation on site. Upon receipt, relays should be examined immediately to ensure no damage has been sustained in transit. If damage has been sustained during transit a claim should be made to the transport contractor and Schneider Electric should be promptly notified.
Relays that are supplied unmounted and not intended for immediate installation should be returned to their protective polythene bags.
1.2 Electrostatic discharge (ESD)
The relays use components that are sensitive to electrostatic discharges.
The electronic circuits are well protected by the metal case and the internal module should not be withdrawn unnecessarily. When handling the module outside its case, care should be taken to avoid contact with components and electrical connections. If removed from the case for storage, the module should be placed in an electrically conducting antistatic bag.
There are no setting adjustments within the module and it is advised that it is not unnecessarily disassembled. Although the printed circuit boards are plugged together, the connectors are a manufacturing aid and not intended for frequent dismantling; in fact considerable effort may be required to separate them. Touching the printed circuit board should be avoided, since complementary metal oxide semiconductors (CMOS) are used, which can be damaged by static electricity discharged from the body.
P92x/EN GS/I52 Technical Guide Getting Started Page 4/18 MiCOM P921-P922-P923
2. HANDLING OF ELECTRONIC EQUIPMENT
A person’s normal movements can easily generate electrostatic potentials of several thousand volts. Discharge of these voltages into semiconductor devices when handling electronic circuits can cause serious damage, which often may not be immediately apparent but the reliability of the circuit will have been reduced.
The electronic circuits are completely safe from electrostatic discharge when housed in the case. Do not expose them to risk of damage by withdrawing modules unnecessarily.
Each module incorporates the highest practicable protection for its semiconductor devices. However, if it becomes necessary to withdraw a module, the following precautions should be taken to preserve the high reliability and long life for which the equipment has been designed and manufactured.
1. Before removing a module, ensure that you are at the same electrostatic potential as the equipment by touching the case which is connected to the protective conductor terminal.
2. Handle the module by its front plate, frame or edges of the printed circuit board. Avoid touching the electronic components, printed circuit track or connectors.
3. Do not pass the module to another person without first ensuring you are both at the same electrostatic potential. Shaking hands achieves equipotential.
4. Place the module on an antistatic surface, or on a conducting surface which is at the same potential as yourself.
5. Store or transport the module in a conductive bag.
If you are making measurements on the internal electronic circuitry of an equipment in service, it is preferable that you are earthed to the case with a conductive wrist strap. Wrist straps should have a resistance to ground between 500kΩ – 10MΩ.
If a wrist strap is not available you should maintain regular contact with the case to prevent a build-up of static. Instrumentation which may be used for making measurements should be earthed to the case whenever possible.
More information on safe working procedures for all electronic equipment can be found in BS5783 and IEC 147-OF. It is strongly recommended that detailed investigations on electronic circuitry or modification work should be carried out in a special handling area such as described in the above-mentioned BS and IEC documents.
Technical Guide P92x/EN GS/I52 Getting Started MiCOM P921-P922-P923 Page 5/18
3. RELAY MOUNTING
Relays are dispatched either individually or as part of a panel/rack assembly.
If an MMLG test block is to be included it should be positioned at the right-hand side of the assembly (viewed from the front). Modules should remain protected by their metal case during assembly into a panel or rack.
For individually mounted relays an outline diagram is supplied in chapter 2 of this Technical Guide showing the panel cut-outs and hole centres.
P92x/EN GS/I52 Technical Guide Getting Started Page 6/18 MiCOM P921-P922-P923
4. UNPACKING
Care must be taken when unpacking and installing the relays so that none of the parts is damaged or the settings altered. Relays must only be handled by skilled persons. The installation should be clean, dry and reasonably free from dust and excessive vibration. The site should be well lit to facilitate inspection. Relays that have been removed from their cases should not be left in situations where they are exposed to dust or damp. This particularly applies to installations which are being carried out at the same time as construction work.
Technical Guide P92x/EN GS/I52 Getting Started MiCOM P921-P922-P923 Page 7/18
5. STORAGE
If relays are not to be installed immediately upon receipt they should be stored in a place free from dust and moisture in their original cartons. Where de-humidifier bags have been included in the packing they should be retained. The action of the de-humidifier crystals will be impaired if the bag has been exposed to ambient conditions and may be restored by gently heating the bag for about an hour, prior to replacing it in the carton.
Dust which collects on a carton may, on subsequent unpacking, find its way into the relay; in damp conditions the carton and packing may become impregnated with moisture and the de-humifier will lose its efficiency.
Storage temperature: –25°C to +70°C.
Sustained exposure to high humidity during storage may cause damage to electronics and reduce the lifetime of the equipment.
Therefore, once the MiCOM products have been unpacked, we recommend that they are energized within the three following months.
Where electrical equipment is being installed, sufficient time should be allowed for acclimatisation to the ambient temperature of the environment, before energisation.

6. INTRODUCTION TO THE MiCOM P921-P922-P923 RELAYS
The range of MiCOM protection relays follows on from the success of the MIDOS, K and MODN ranges by incorporating the last changes in digital technology. The relays MiCOM P921-P922 and P923 are fully compatible and use the same modular box concept. The MiCOM P921-P922 and P923 of relays provides more protection for the most demanding applications.
Each relay has a large number of functions for controlling and collecting data. This can form part of a fully integrated system covering protection, control, instrumentation, data acquisition and the recording of faults, events and disturbances. The relays are equipped on the front panel with a liquid crystal display (LCD) with 2 x 16 back-lit alphanumerical characters, a tactile 7 button keypad (to gain access to all the parameters, alarms and measurements) and 8 LEDs simply displaying the state of the MiCOM P921-P922 and P923 relays. In addition, the use of the RS485 communication port makes it possible to read, reinitialise and change the settings of the relays, if required, from a local or remote PC computer equipped with appropriate software.
Its flexibility of use, reduced maintenance requirements and ease of integration allow the MiCOM P921-P922 and P923 to provide an evolving solution for the problems of the protection of electric networks.
The MiCOM P921-P922 and P923 relays provide comprehensive voltage and frequency protection for phase and ground faults together with measurements, control and recording facilities.

− a 9-pin female D-type front port for communication with a PC locally to the relay (up to 15m distance) via a RS232 serial data connection (SK1 port).
The fixed function LEDs on the left hand side of the front panel are used to indicate the following conditions:
LEDS Colour Labels Significance
LED1 Red Trip. LED 1 indicates when a trip order has been issued by the relay to the cut-off element (circuit breaker, contactor). This LED recopies the trip order issued to the trip output contact (RL1). Its normal state is unlit. It is illuminated as soon as a trip order is issued. It goes out when the associated alarm is acknowledged (by pushing the key).
LED2 Yellow Alarm LED 2 indicates that an alarm has been registered by MiCOM P921, P922 or P923 relays. The alarms are either threshold crossings (instantaneous), or tripping orders (time delayed). The LED will flash until the alarms have been accepted (read), after which the LED will change to constant illumination, and will extinguish when the alarms have been cleared.
LED3 Orange Equip Failure LED 3 is dedicated to the internal alarms of MiCOM P921, P922 and P923 relays. When a « non critical » internal alarm (typically communication Fault) is detected, the LED flashes continuously. When the Fault is classed as « critical », the LED is illuminated continuously. The extinction of this LED is only possible by the disappearance of the cause that caused its function (repair of the module, disappearance of the Fault).
LED4 Green Aux Supply LED 4 indicates that MiCOM P921, P922 and P923 relays are in correct working order.
LED5 to LED8
Red Aux1 to Aux4 These LEDs can be programmed by the user on the basis of information on available thresholds (instantaneous and time-delayed). The user selects the information he wishes to see associates with each LED from the menu element (Logic OR). Each LED illuminates when the associated information is valid. The extinction of each LED is linked to the acknowledgement of the associated alarms.

2. PORTS CONNECTION
2.1 Front port connection (RS232)
The front communication port is provided by a 9-pin female D-type connector located under the bottom hinged cover. It provides RS232 serial data communication (asynchronous RS232 connection according the IEC870 requirements) and is intended for use with a PC locally to the relay (up to 15m distance).
The relay is a Data Communication Equipment (DCE) device. Thus the pin connections of the relay’s 9-pin front port are as follows:
Pin no. 2 Tx Transmit data
Pin no. 3 Rx Receive data
Pin no. 5 0V Zero volts common
None of the other pins are connected in the relay. The relay should be connected to the serial port of a PC, usually called COM1 or COM2. PCs are normally Data Terminal Equipment (DTE) devices which have a serial port pin connection as below (if in doubt check your PC manual):
Pin no. 2 Rx Receive data
Pin no. 3 Tx Transmit data
Pin no. 5 0V Zero volts common
For successful data communication, the Tx pin on the relay must be connected to the Rx pin on the PC, and the Rx pin on the relay must be connected to the Tx pin on the PC, as shown in figure 5. Therefore, providing that the PC is a DTE with pin connections as given above, a ‘straight through’ serial connector is required, i.e. one that connects pin 2 to pin 2, pin 3 to pin 3, and pin 5 to pin 5. Note that a common cause of difficulty with serial data communication is connecting Tx to Tx and Rx to Rx. This could happen if a ‘cross-over’ serial connector is used, i.e. one that connects pin 2 to pin 3, and pin 3 to pin 2, or if the PC has the same pin configuration as the relay.

The total communication cable from the master unit to the farthest slave device is a spur, and no branches may be made from this spur. The maximum cable length is 1000m and the maximum number of devices per spur is 32.
The transmission wires should be terminated using a 150 Ω resistor at both extreme ends of the cable. To do this, connect the terminals 30 and 32 together.

1. INTRODUCTION TO THE USER INTERFACES AND SETTINGS OPTIONS
MiCOM P921 P922 and P923 are fully numerical relays designed to perform electrical protection and control functions.
The following section describes the MiCOM P92x range and the main differences between the different models.
MiCOM relays are powered either from a DC (2 voltage ranges) or an AC auxiliary power supply.
Using the front panel, the user can easily navigate through the menu and access data, change settings, read measurements, etc.
Eight LEDs situated in the front panel help the user to quickly know the status of the relay and the presence of alarms. Alarms that have been detected are stored and can be displayed on the back-lit LCD.
Any short time voltage interruption (<50ms) is filtered and regulated through the auxiliary power supply.
Output relays are freely configurable and can be activated by any of the control or protection functions available in the relay. Logic inputs can also be assigned to various control functions.
On their rear terminals MiCOM P921 P922 and P923 have a standard RS485 port available. When ordering, the user can choose between the following communication protocol: ModBus RTU, IEC 60870-5-103, Courier or DNP3.0.
The relay has three user interfaces:
− The front panel user interface via the LCD and keypad.
− The front port which supports ModBus communication.
− On their rear terminals MiCOM P921 P922 and P923 have a standard RS485 port available. When ordering, the user can choose between the following communication protocol: ModBus RTU, IEC 60870-5-103, Courier or DNP3.0.
Using RS485 communication channel, all stored information (measurements, alarms, and parameters) can be read and settings can be modified when the chosen protocol allows it.
Reading and modification of this data can be carried out on site with a standard PC loaded with MiCOM S1 setting software.
Thanks to its RS485 based communication, MiCOM P921, P922 and P923 relays can be connected directly to a digital control system. All the available data can then be gathered by a substation control system and be processed either locally or remotely.

FIGURE 1: MiCOM P921, P922 AND P923 FRONT PANEL DESCRIPTION
The front panel of the relay has three separate sections:
1. The LCD display and the keypad,
2. The LEDs
3. The two zones under the upper and lower flaps.
NOTE: Starting from Hardware 5, there is no need of battery in the front of the relay. Indeed, disturbance, fault and event records are stored on a flash memory card that doesn’t need to be backed up by a battery. The compartment is fitted with a blanking cover.
1.1.3 LCD display and keypad description
The front panel components are shown below. The front panel functionality is identical for the P921, P922 & P923 relays.
Technical Guide P92x/EN FT/I52 User Guide MiCOM P921/P922 & P923 Page 9/72
1.1.3.1 LCD display
In the front panel, a liquid crystal display (LCD) displays settings, measured values and alarms. Data is accessed through a menu structure.
The LCD (alphanumeric or with graphic interface option) has two lines, with sixteen characters each. A back-light is activated when a key is pressed and will remain lit for five minutes after the last key press. This allows the user to be able to read the display in most lighting conditions.
1.1.3.2 Keypad
The keypad has seven keys divided into two groups:
• Two keys located just under the screen (keys and ).
Keys and are used to read and acknowledge alarms. To display successive alarms, press key . Alarms are displayed in reverse order of their detection (the most recent alarm first, the oldest alarm last). To acknowledge the alarms, the user can either acknowledge each alarm using or go to the end of the ALARM menu and acknowledge all the alarms at the same time.
When navigating through submenus, key is also used to come back to the head line of the corresponding menu.
NOTE: To acknowledge a relay latched refer to the corresponding submenu section.
• Four main keys , , , located in the middle of the front panel.
They are used to navigate through the different menus and submenus and to do the setting of the relay.
The key is used to validate a choice or a value (modification of settings).
P92x/EN FT/I52 Technical Guide User Guide Page 10/72 MiCOM P921/P922 & P923
1.1.4 LEDs
The LED labels on the front panel are by default written in English, however the user has self-adhesive labels available with MiCOM relays on which it is possible to write using a ball point pen.
The top four LEDs indicate the status of the relay (Trip condition, alarm LED, equipment failure, auxiliary supply).
The four lower LEDs are freely programmable by the user and can be assigned to display a threshold crossing for example (available for all models) or to show the status of the logic inputs.The description of each one of these eight LEDs located in the left side of the front view is given hereafter (numbered from the top to bottom from 1 to 8):
LED 8
LED 1
P3951ENa
LED 1 Colour: RED Label: Trip
LED 1 indicates that the relay has issued a trip order to the cut-off element (circuit breaker, contactor). This LED recopies the trip order issued to the Trip logic output. Its normal state is unlit. As soon as a triggering order is issued, the LED lights up. It is cleared when the associated alarm is acknowledged either through the front panel, or by a remote command, a digital input, or by a new fault (CONFIGURATION/Alarms menu).
LED 2 Colour: ORANGE Label: ALARM
LED 2 indicates that the relay has detected an alarm. This alarm can either be a threshold crossing (instantaneous), or a trip order (time delayed). As soon as an alarm is detected, the LED starts blinking. After all the alarms have been read, the LED lights up continuously.
After acknowledgement of all the alarms, the LED is extinguished.
The alarm LED can be reset either through the front panel, or by remote command, by a digital input., etc.
LED 3 Colour: ORANGE Label: Warning
LED 3 indicates internal alarms of the relay. When the relay detects a « non critical » internal alarm (typically a communication failure), the LED starts blinking continuously. When the relay detects a fault that is considered as « critical », the LED lights up continuously. Only the disappearance of the cause of the fault can clear this LED (repair of the module, clearance of the Fault).
Technical Guide P92x/EN FT/I52 User Guide MiCOM P921/P922 & P923 Page 11/72
LED 4 Colour: GREEN Label: Healthy
LED 4 indicates that the relay is powered by an auxiliary source at the nominal range.
LED 5 to 8 Colour: RED Label: Aux.1 to 4.
These LEDs are user programmable and can be set to display information about instantaneous and time-delayed thresholds as well as the status of the logic inputs. Under the CONFIGURATION/LED menu of the relay, the user can select the information he wishes to associate with each LED. He can affect more than one function to one LED. The LED will then light up when at least one of the associated information is valid (OR gate). The LED is cleared when all the associated alarms are acknowledged.
1.1.5 Description of the two areas under the top and bottom flaps
1.1.5.1 Relay Identification
Under the upper flap, a label identifies the relay according to its model number (order number) and its serial number. This information defines the product in a way that is unique. In all your requests, please make reference to these two numbers.
Under the model and serial number, you will find information about the level of voltage of the auxiliary supply and the nominal earth current value.
1.1.5.2 Lower flap
Under the lower flap, a RS232 port is available in all MiCOM relays. It can be used either to download a new version of the application software version into the relay flash memory or to download/retrieve settings plugging a laptop loaded with MiCOM S1 setting software.
To withdraw more easily the active part of the MiCOM relay (i-e the chassis) from its case, open the two flaps, then with a 3mm screwdriver, turn the extractor located under the upper flap, and pull it out of its case pulling the flaps towards you.
1.1.6 The USB/RS232 cable (to power and set the relay)
The USB/RS232 cable is able to perform the following functions:
1. It is able to power the relay from its front port. This allows the user to view or modify data on the relay even when the auxiliary power supply of the relay has failed or when the relay is not connected to any power supply. The USB port of the PC supplies the power necessary to energize the relay. This lasts as long as the battery of the PC can last.
2. It provides an USB / RS 232 interface between the MiCOM relay and the PC. This allows the user to be able to change the setting of the relay using a PC with its USB port.
It eases the use of the relay allowing the retrieval of records and disturbance files for example when the auxiliary supply has failed or is not available.
The associated driver (supplied with the relay) needs to be installed in the PC. For more information, refer to MiCOM E2 User Guide.
P92x/EN FT/I52 Technical Guide User Guide Page 12/72 MiCOM P921/P922 & P923
1.2 Menu structure
The relay’s menu is arranged in a tabular structure. Each setting in the menu is referred to as a cell, and each cell in the menu may be accessed by reference to a row and column address. The settings are arranged so that each column contains related settings, for example all of the disturbance recorder settings are contained within the same column. As shown in the figure, the top row of each column contains the heading that describes the settings contained within that column. Movement between the columns of the menu can only be made at the column heading level. A complete list of all of the menu settings is given in the Menu Content tables (P92x/EN HI section).

1.3 PASSWORD
1.3.1 Password protection
A password is required for relay settings, especially when changing the various thresholds, time delays, communication parameters, allocation of inputs and outputs relays.
The password consists of four capital characters. When leaving factory, the password is set to AAAA. The user can define his own combination of four characters.
Should the password be lost or forgotten, the modification of the stored parameters is blocked. It is then necessary to contact the manufacturer or his representative and a stand-by password specific to the relay may be obtained.
The programming mode is indicated with the letter "P" on the right hand side of the display on each menu heading. The letter "P" remains present as long as the password is active (5 minutes if there is no action on the keypad).
Technical Guide P92x/EN FT/I52 User Guide MiCOM P921/P922 & P923 Page 13/72
1.3.2 Password entry
The input of the password is requested as soon as a modification of a parameter is made for any one of the six/eight menus and the submenus. The user enters each one of the 4 characters and then validates the entire password with .
After 5 seconds, the display returns to the point of the preceding menu.
If no key is pressed inside of 5 minutes, the password is deactivated. A new password request is associated with any subsequent parameter modification.
1.3.3 Changing the password
To change an active password, go to the OP. PARAMETERS menu and then to the Password submenu. Enter the current password and validate it. Then press and enter the new password character by character and validate the new password using .
The message NEW PASSWORD OK is displayed to indicate that the new password has been accepted.
1.3.4 Change of setting invalidation
The procedure to modify a setting is described in the following sections of this manual.
If there is a need to get back to the old setting push key before validating the setting change. The following message will then appear on the LCD for a few seconds and the old setting will remain unchanged.
UPGRADE CANCEL
1.4 Displays of Alarm & Warning Messages
Alarm messages are displayed directly on the front panel LCD. They have priority over the default display presenting measured current values. As soon as the relay detects an alarm condition (crossing of a threshold for example), the associated message is displayed on the front panel LCD and the LED Alarm (LED 2) lights up.
Alarms
We distinguish two types of alarm and warning messages:
- Alarm messages generated by the electrical power network.
- Warning messages caused by hardware or software faults from the relay.
The alarm messages can either be self-resetting or latched, in which case they must be cleared manually. To view the alarm messages press the key . When all alarms have been viewed, but not cleared, the alarm LED will change from flashing to constant illumination. To scroll through these pages, press the key. The oldest alarm will be displayed on the last page, the most recent one on the first page: each message will be identified by a number. When all pages of the fault record have been viewed, the following prompt will appear:
Clear All Alarms
P92x/EN FT/I52 Technical Guide User Guide Page 14/72 MiCOM P921/P922 & P923
To clear all alarm messages press ; to return to the display of the first alarm message and leave the alarms uncleared, press . There is no need to enter a password before the alarm messages can be cleared. When the alarms have been cleared the yellow alarm LED will extinguish, as will the red trip LED if it was illuminated following a trip.
The alarm messages are classified as indicated below:
• Electrical system alarms,
• Relay hardware or software alarms.
1.4.1 Electrical Network Alarms
Any crossing of a threshold (instantaneous or time delay) generates an "electrical network alarm". The involved threshold is indicated. Regarding the phase thresholds, the phase designation (A, B or C) is also displayed.
For example:
V< 2/3 PHASE AB BC CA
NOTE: instantaneous information leads to a self-resetting alarm message. The alarm LED will then be switched off as soon as the instantaneous information has disappeared.
If several alarms are triggered, they are all stored in their order of appearance and presented on the LCD in reverse order of their detection (the most recent alarm first, the oldest alarm last). Each alarm message is numbered and the total number of alarm messages is displayed.
The user can read all the alarm messages pressing .
The user acknowledges and clears the alarm messages from the LCD pressing .
The user can acknowledge each alarm message one by one or all by going to the end of the list to acknowledge, and clear, all the alarm messages pressing .
The control of the ALARM LED (LED 2) is directly assigned to the status of the alarm messages stored in the memory.
If one or several messages are NOT READ and NOT ACKNOWLEDGED, the ALARM LED (LED 2) flashes.
If all the messages have been READ but NOT ACKNOWLEDGED, the ALARM LED (LED 2) lights up continuously.
If all the messages have been ACKNOWLEDGED, and cleared, if the cause that generated the alarm disappears, the ALARM LED (LED 2) is extinguished.
1.4.2 Relay Hardware or Software Warning Messages
Any software or hardware fault internal to MiCOM relay generates a "hardware/software alarm" that is stored in memory as a "Hardware Alarm". If several hardware alarms are detected, they are all stored in their order of appearance. The warning messages are presented on the LCD in reverse order of their detection (the most recent first and the oldest last). Each warning message is numbered and the total stored is shown.
Technical Guide P92x/EN FT/I52 User Guide MiCOM P921/P922 & P923 Page 15/72
If an hardware error appears, the following prompt will appear:
HARDWARE ALARMS
The user can read all warning messages pressing , without entering the password: for example,
STATS ERROR 1/1
It is not possible to acknowledge and clear warning messages caused by internal relay hardware or software failure. This message can only be cleared once the cause of the hardware or software failure has been removed.
The control of the WARNING LED (LED 3) is directly assigned to the status of the warning messages stored in the memory.
Alarms can be classified as minor or major faults. If the internal hardware or software failure is major (i.e. the relay cannot perform protection functions), the WARNING LED (LED 3) lights up continuously.
− major fault: Protection and automation functions of the equipment are blocked. In this condition, the protection relay detects the corresponding fault and activates RL0 Watchdog relay (35-36 terminals contact is closed – “relay failed” position). For instance: the “DEF. ANA” fault (fault in the analog circuit channel) is considered as a major fault because the protection functions will not operate correctly.
− minor fault: Protection and automation functions of the relay operate. A minor fault will not activate RL0 Watch Dog relay (35-36 terminals contact is closed, 36-37 terminals is open). This fault causes a LED alarm and is displayed on the LCD panel.
The Watch Dog relay controls the correct operation of the protection and automation function. This relay fault “RL0 relay” is activated if the following functions or checks are faulty:
− microprocessor operation,
− power supply check,
− reconstituted internal power supply check,
− heating of a circuit board component monitoring,
− analog channel monitoring (acquisition sampling),
− programm execution monitoring,
− communication ports monitoring.
If the internal hardware or software failure is minor (like a communication failure that has no influence on the protection and automation functions), the WARNING LED (LED 3) will flash.
Possible Hardware or Software alarm messages are:
P92x/EN FT/I52 Technical Guide User Guide Page 16/72 MiCOM P921/P922 & P923

This menu allows the user to select the number of cycle to be involved in the calculation of the rate of change of frequency elements, and the number of confirmation of calculation for positionning the protection.
In fact, the instantaneous element is positionned after exceeding the threshold for a programmable number of df/dt function calculation.
This number of confirmation is 2 or 4.
In addition, it allows the configuration of the undervoltage blocking element.
When the input voltage value is unsufficient this will lead to irregular behavior and it is imaginable that the frequency elements could mal operate.
This is important during line energization, de-energization or a generator acceleration where significant distortion can be experienced. To prevent the mal operation, all the frequency elements and related thresholds are blocked by mean of an adjustable U/V blocking function.
To gain access to the “FREQ” submenu from the “CONFIGURATION” menu, press followed by or until the desired submenu header is displayed.

2.5 Communication
2.5.1 Rear communication port description
The rear communication port is provided by a 3-terminal screw connector located on the back of the relay.
The rear port provides RS485 serial data communication and is intended for use with a permanently-wired connection to a remote control centre. Of the three connections, two are for the signal connection which can be connected either way round, and the other is for the earth shield of the cable.
The rear RS485 interface is isolated and is suitable for permanent connection whichever protocol is selected. The advantage of this type of connection is that up to 32 relays can be ‘daisy chained’ together using a simple twisted pair electrical connection.
All the connections are described in details into the Chapter 2 of this Technical Guide.
2.5.2 Rear and front communication management
2.5.2.1 Modification through the front panel
If there is any modification of the settings done through the front panel, a downloading of a new settings file via the MiCOM S1 software (locally), or via a remote master station will be forbidden.
The change of settings will be possible as soon as the setting mode will elapse (at the end of the 5mn timer or after power off/power on of the relay).
2.5.2.2 Modification through the MiCOM S1 software (front port, RS232)
If there is any modification of the settings through the MiCOM S1 software, a modification through the front panel will be forbidden and the following message will appear:

2.5.3 HMI description
The « COMMUNICATION » menu depends on the rear communication protocol which is implemented into the MiCOM relay. This protocol must be selected at the order among the following protocols: Kbus/Courier, Modbus, IEC60870-5-103. Please refer to the cortec page (Chapter 3 of this Technical Guide).
2.5.3.1 Courier Interface
Courier is the communication language developed to allow remote interrogation of its range of protection relays. Courier works on a master/slave basis where the slave units contain information in the form of a database, and respond with information from the database when it is requested by a master unit.
The relay is a slave unit which is designed to be used with a Courier master unit such as MiCOM S1, MiCOM S10, PAS&T, ACCESS or a SCADA system. MiCOM S1 is a Windows 98 and NT compatible software package which is specifically designed for setting changes with the relay.
To gain access to the “COMMUNICATION” menu from the default display, press once and 3 times. The HMI is described below:

COMMUNICATION ? YES
Description: enable/disable the "COMMUNICATION" functionRange: YES/NO
RELAY ADDRESS 1

2.5.3.2 Modbus interface
Modbus is a master/slave communication protocol which can be used for network control. In a similar fashion to Courier, the system works by the master device initiating all actions and the slave devices (the relays) responding to the master by supplying the requested data or by taking the requested action. Modbus communication is achieved via a twisted pair connection to the rear port and can be used over a distance of 1000m and up to 32 slave devices.

2.6.3 Zero sequence overvoltage (neutral displacement) protection
The zero sequence overvoltage element functions according to the VT configuration.
− VT configuration = 3Vpn + Vr, 3Vpp + Vr or 2Vpp + Vr, then the [59N] will operate based on the residual voltage (due to the summation of the 3 phase voltages), measured on relay terminals (49-50).
− VT configuration = 3Vpn, then [59N] will operate based on the zero sequence
voltage V0= (Ua + Ub + Uc)
3 calculated internally.
The inverse characteristic (only for the 1st stage) is given by the following formula:
t = K / (1 – M)
Where, K = Time Multiplier Setting t = operating time in seconds M = Applied input voltage / Relay setting voltage (Vs)
When residual voltage cannot be measured, the derived V0 sequence protection (V0der>, P922 and P923 only) depends only on the connection mode and
calculation based on the phase voltage ((Ua + Ub + Uc)
3 calculation).
Technical Guide P92x/EN FT/I52 User Guide MiCOM P921/P922 & P923 Page 41/72
− If VT configuration = 3 Vpn+Vr", 3Vpp + Vr or 2Vpp + Vr, the derived V0 sequence voltage is calculated,
− If VT configuration is 3 Vpn, then, the derived V0 sequence voltage threesholds are equal to the residual voltage threesholds.

2.6.6 Frequency protection (MiCOM P922 and P923)
The principle of measurement of frequency is based in general on the measurement of time every cycle, thus a new measurement is started at each voltage zero crossing. Numerical filters are used to minimize the harmonics influence. Frequency threshold is validated after a number of periods set in the Configuration menu (‘F : Validat. Nb =’ setting, MiCOM P923).
Precautions have been made to make this mode of calculation insensitive to the vector shifts and phases jumps.
This function will be inhibited if the voltage level for each phase is below the blocking minimum voltage. This voltage is settable (P923) in the CONFIGURATION menu (5 to 130V for range 1 and 20 to 480V for range 2).

2.6.7 Rate of change of frequency (MiCOM P923 only)
The calculation of the rate of change of frequency is an average measurement of the instantaneous values over a programmable number of cycles (1 to 200); refer to the "CONFIGURATION" menu. The instantaneous values of rate of change of frequency are measured every cycle. The rate of change of frequency elements are very important to detect any active power loss under severe disturbances: they can be used for load shedding schemes. These elements offer the possibility to detect the tendency of the variation of frequency, and thus re establish the correct load/generation without waiting for big frequency reduction. These elements could be combined to the frequency elements using the AND logic equations, or using the “F+df/dt in the AUTOMAT. CTRL menu (MiCOM P923), to provide a very usefull mechanism allowing a more secure trip decision to be achieved during transient system disturbances.
This function will be inhibited if the voltage level for each phase is below the settable undervoltage blocking value (see menu "CONFIGURATION", submenu "FREQ and df/dt CONFIG").
The information "freq out of range" will be generated:
− in the above mentioned application
− if the frequency is out of Range: fmeasured > (fn+20Hz) or fmeasured < (fn–20Hz)
The following HMI description is given for df/dt1 “change of requency”. These menus are identical for df/dt2, df/dt3, df/dt4, df/dt5 and df/dt6 rates.

2.6.8 “DELTA U / DELTA T” submenu (MiCOM P923 only)
“Delta U / Delta t” protects the circuit against voltage variations.
This menu is useful to detect a voltage variation (load variation):
− A fast voltage drop or increase, exceeding user’s threholds can be used as an alarmor to trip the protection,
− A slow voltage variation can be associated to another threshold (as U>, U>…) in a boolean equation.
“Delta U / Delta P” allows 4 independant settings, giving you a a largest flexibility for your application: For instance, you can monitor a minimum and a maximum voltage variation, for positive and negative voltages. The four thresholds can be independently used.

2.7.11 "CB SUPERVISION" Submenu
This submenu makes it possible to validate the circuit breaker supervision and monitoring functions, and the various settings associated to these functions.
In the MiCOM P921 – P922 and P923 relays, the control of the circuit breaker can be done:
• Tripping order: the tripping order is realized by using the dedicated trip output contact (RL1). This command is maintained during the specified “TRIP PULSE TIME”. The command can be generated by a protective function of the relay: it can also be done via a logic input (select the “AUX1” logic input and assign the "tAUX1" to the trip output relay), or via the local/remote communication (see chapter 6 of this Technical Guide),
• Closing order: 2 different ways can be used. - This order is realized by using the output contact, which has
been configured for this closing order (see "AUX OUTPUT RLY" menu, "CLOS. CB" cell). This command is maintained during the specified "CLOSE PULSE TIME". The command can only be generated via the local/remote communication (see section 2.5).
- This order can also be realized by using one logic input (select the "AUX2 logic input) which can be assigned to any of the output contacts. This command will be maintained as long as the logic input is energized.
Moreover, the MiCOM P922-P923 relays offer the supervision of the closing/opening time of the circuit breaker. They also include the supervision of the number of CB operations, with a settable threshold of the maximum allowed operations.

3. WIRING
MiCOM P92x range of relays have the same terminal layout for common elements. The wiring diagram for each model is provided in Appendix 1 of the Technical Guide.
3.1 Auxiliary supply
The auxiliary power supply for the MiCOM P921, P922 & P923 relays can be either direct current with a voltage range of 24-60 VDC, 48-250 VDC,or alternative current with a voltage range of 48-250 VAC/ 50-60 Hz. The voltage range (Ua) is specified on the adhesive paper label under the top hinged cover on the front of the relay.
The auxiliary power supply must be connected only to terminals 33 and 34.
3.2 Voltage measurement inputs
MiCOM P921, P922 and P923 have 3 phase and 1 earth voltage inputs available.
3.3 Logic inputs
The number of logic inputs depends on the relay model. The relays have programmable opto-isolated logic inputs, which can be assigned to any available label or function. Logic inputs for each relay model:
Model P921 P922 P923
Logic outputs 2 5 5
The voltage range of the inputs is identical to the DC (or AC) auxiliary supply range of the MiCOM relay (e.g. Uaux = 24-250 Vdc, logic input voltage range = 24-250 Vdc).
On the same MiCOM P92x relay, the user can mix different voltage levels for the logic inputs (e.g. Uaux = 24-250 Vdc, Input 1= 48 Vdc, Input 2-5= 110 Vdc).
If the user sets the supply of the logic input as AC they are active from 24 to 240Vac.
The automation functions that can be assigned to these logic inputs can be selected from the AUTOMAT. CTRL Menu.
NOTE: Do not forget to select in the CONFIGURATION/Configuration Inputs Menu weither the voltage input is "AC" or "DC". .
3.4 Output relays
The number of logic outputs depends on the relay model. The relays have configurable logic outputs, which can be assigned to any available function.
The number of logic outputs available for each relay model is presented in the following table:
Model P921 P922 P923
Logic outputs 5 8 8
The first logic output (RL0) is dedicated to indicate a relay fault (Watchdog, WD) and is not part of this table.
The normally closed (NC) contact of the Watchdog (RL0) can not be configured. The other contacts can be configured to be activated on activation of the different functions available in the relay. A basic output matrix is included in the relay.
Technical Guide P92x/EN FT/I52 User Guide MiCOM P921/P922 & P923 Page 71/72
Some logic outputs have changeover contacts (RL1 and RL2). The other relays (RL3, to RL 8) are normally open contacts.
The protection and control functions that can be assigned to these output relays can be selected from the AUTOMAT. CTRL Menu.
3.5 Communication
3.5.1 RS485 rear communication port
All MiCOM relays have an RS485 rear communication port.
The terminals 29-30-31-32 are dedicated to the RS485 communication port. See wiring diagrams in chapter P92x/EN CO of the Technical Guide.
3.5.2 RS232 front communication port (P921, P922, P923)

1. MODBUS PROTOCOL
The MiCOM P921-P922-P923 relays offer MODBUS TM RTU mode communication via a rear RS485 port.
1.1 MODBUS communication characteristics
1.1.1 MODBUS network characteristics
The MODBUS protocol is based on the master-slave principle with the MiCOM P921, P922 or P923 relay operating as a slave device.
The MODBUS protocol allows the master to read and to write one or several bits, or one or several words, and to control remotely the event logging data.
Access to the network can be:
− either using the query/response principle
SlaveMiCOM P921 n˚1
SlaveMiCOM P923 n˚2
SlaveMiCOM P122 n˚3
Response
Query
Master
P0410 ENa
− or broadcasting a message from the master to all the slave relays.
SlaveMiCOM P921 n˚1
SlaveMiCOM P923 n˚2
SlaveMiCOM P123 n˚3
Broadcast
Master
P0411ENa
In the latter case:
− Broadcast messages are compulsory "write orders",
− Slaves never emit a response to the master,
− RTU protocol mode is used. Each byte of the data frame is coded according to a hexadecimal base.
− At the end of each frame, two bytes are used for CRC16 validity checksum.
P92x/EN CT/I52 Technical Guide Modbus Protocol Page 6/136 MiCOM P921-P922-P923
1.1.2 Parameters of the MODBUS connection
The MODBUS protocol characteristics are:
− Isolated two-point RS485 connection (2kV 50Hz).
− MODBUS line protocol in RTU mode.
− Baud rate available (set using front panel):
Baud rate 300 600 1200 2400 4800 9600 19200 38400
Transmission mode:
Transmission mode 1 start / 8 bits / 1 stop: total 10 bits 1 start / 8 bits / even parity / 1 stop: total 11 bits 1 start / 8 bits / odd parity / 1 stop: total 11 bits 1 start / 8 bits / 2 stop: total 11 bits
1.1.3 Synchronisation of messages
Any 3-bytes length message received after a silence, is considered as a frame start.
1.1.4 Message validity check
The validation of a trame is performed with a 16-bit cyclical redundancy check (CRC). The generator polynomial is:
1 + x² + x15 + x16 = 1010 0000 0000 0001 binary = A001h
1.1.5 Address of the MiCOM relays
The address of the MiCOM relay on a same MODBUS network is situated between 1 and 255. The address 0 is reserved for the broadcast messages.
1.2 MODBUS functions on the MiCOM relays
The MODBUS functions implemented on the MiCOM relays are:
− Function 1 or 2: Reading of n bits
− Function 3 or 4: Reading of n words
− Function 5: Writing of 1 bit
− Function 6: Writing of 1 word
− Function 7: Fast reading of 8 bits
− Function 8: Reading of the diagnosis counters
− Function 11: Reading of the Event counter
− Function 15: Writing of n bits
− Function 16: Writing of n words
Technical Guide P92x/EN CT/I52 Modbus Protocol MiCOM P921-P922-P923 Page 7/136
1.3 Presentation of the MODBUS protocol
MODBUS is a master-slave protocol whereby every exchange involves a master query and a slave response.
1.3.1 Frame size received by the MiCOM P92x relay
Frame transmitted by the master (query):
Slave number Function code Information CRC16 1 byte 1 byte n bytes 2 bytes
Slave number:
The slave number is situated between 1 and 255.
Function code:
Requested MODBUS function (1 to 16).
Information:
Contains the parameters of the selected function.
CRC16:
Value of the CRC16 calculated by the master.
NOTE: the MiCOM relay does not respond to globally broadcast frames sent out by the master.
1.3.2 Format of frames sent by the MiCOM P92x relay
Frame sent by the MiCOM relay (response):
Slave number Function code Data CRC16 1 byte 1 byte n bytes 2 bytes
Slave number:
The slave number is situated between 1 and 255.
Function code:
Processed MODBUS function (1 to 16).
Data:
Contains the response data to master query.
CRC16:
Value of the CRC16 calculated by the MiCOM relay.
1.3.3 Messages validity check
When the MiCOM relay receives a master query, it validates the frame:
• If the CRC is false, the frame is invalid. The MiCOM relay does not reply to the query. The master must retransmit its query. Excepting a broadcast message, this is the only case of non-reply by the MiCOM relay to a master query.
• If the CRC is correct but the MiCOM relay can not process the query, it sents to the master a exception response.
Exception frame sent by the MiCOM relay (response):
Slave number Function code Error code CRC16 1 byte 1 byte 1 byte 2 bytes
Slave number:
The slave number is situated between 1 and 255.
P92x/EN CT/I52 Technical Guide Modbus Protocol Page 8/136 MiCOM P921-P922-P923
Function code:
The function code returned by the MiCOM relay in the exception frame is the code in which the most significant bit (bit7) is forced to 1.
Error code:
Among the 8 exception codes of the MODBUS protocol, the MiCOM relay manages two of them:
• code 01: Function code unauthorised or unknown.
• code 03: A value of the data field is unauthorised (incorrect code). − Control of pages being read. − Control of pages being written. − Control of address in pages. − Length of request messages.
CRC16:
The CRC16 value is calculated by the slave.
1.4 Modbus request definition used to retrieve the disturbance records
To retrieve a disturbance record, the following requests must be done in the exact given order:
1. (optional): Send a request to know the number of disturbance records available in the saved RAM.
2. To retrieve the data of one channel:
2a – (compulsory): Send a service request specifying the record number and the channel number which have to be retrieved.
2b – (compulsory): Send requests to retrieve the data of a disturbance record channel as many time as needed.

1. K-BUS PROTOCOL AND COURIER LANGUAGE
The serial communications are transmitted on K-Bus, a multi –drop network proposing an instantaneous interface with the IEC 870-5 FT1.2 standards. The language and the communication protocol used are Courier. this concept permits especially to the generic programs of the principal units to access to a high number of different relays without need to change permanently the principal unit program for each relay type. The relays form a distributed database in which the principal workstation proceeds to a selective call of the slave relays in order to know all necessary information.
Courier is designed to work using a selective call feature which forbids any slave periphery to communicate directly with the central unit when a particular information about an event needs to be transmitted. The slave workstation has to wait that the principal workstation asks for the information. With Courier protocol, each information is given into a box with a code of the length and the database type. By knowing the database format, the reception periphery can read them.
1.1 K-BUS
K-Bus is a communication system developed for connecting the slave peripheries to the central unit, permitting them to execute all remote monitoring and remote control functions using the appropriate communication language. K-Bus is not able to permit a direct communication between the slave peripheries. Only a communication between the central unit and the slave peripheries can be established. The principal characteristics of the K-Bus are the profitability, high security level, his installation facility and his user friendliness.
1.1.1 K-Bus Transmission Layer
The communication port RS485 is based on several levels of reception and transmission voltages with galvanic isolation given by a transformer. A selective call protocol is used. No relay unit is allowed to transmit before having received a validation message without any error detection. The transmission is synchronous on a pair of isolated waves. The data are coded FM0 with a clock signal to eliminate all CC-component, allowing the signal to cross the transformers.
With the exception of the central units, each network node is passive. The defective units can not interfere with the communication established with the other healthy units. The message format is HDLC. The data transmission speed is 64 Kbits/s.
1.1.2 K-Bus Connection
The connection on the K-Bus port is realized by screwed terminals of 4 mm of MIDOS standards or by FASTON-connectors. A cabled pair is sufficient to realize the connection, Knowing that the polarity is not important. It is recommended to use an external screen earth linked at the end of the principal workstation only. The screen has to be fixed with a M4 screw following the wiring scheme. The functioning of the K-BUS network is guaranteed for 32 units connected on 1000 meters of cables. Thanks to the data code method, the polarity of the Bus cable connection is not important.
Note: the K-Bus network has to finish with a 150 ohms resistance on each end of the bus. The principal workstation can be placed anywhere on the network. This command point has to be unique.
1.1.3 Auxiliary equipment
For communication with the relay it is necessary to have at least one converter case K-Bus/IEC870-5 of the type KITZ and a computer suitable software, an interconnection cable RS232 for connecting the KITZ to the computer and a software conform to the specification of the Courier protocol.
1.2 Relay Courier Database
The Courier database is two dimensional structure with each cell in a database being referenced by a row and a column address. Both the column and the row can take a range from 0 to 255. Addresses in the database are specified as hexadecimal values, eg 0A02 is column 0A ( 10 decimal ) row 02. Associated settings /data will be part of the same column, row zero of the column contains a text string to identify the contents of the column.
This database is given in section 2.

1.2.2 List of events generated by the relay MiCOM P922 and P923
See Format F107 described in MODBUS section.
NOTE: When the cell reference is different from 0, this means that an event is generated the event takes place and another event is generated when the event disappears.
When the cell reference is equal to zero, only the event is generated.
Twelve bits are available in the character String to describe the content of a Courier cell.
When the event appears, the corresponding bit of the associated format changes to “1”.
When the event disappears, the corresponding bit of the associated format changes to “0”.
1.3 Setting Changes
This uses a combination of three commands to perform a settings change:
Enter Setting Mode- checks that the cell is settable and returns to the limits.
Pre-load Setting- Place a new value in the cell, this value is echoed to ensure that no setting changes has taken place, the confirmation of the new setting value does not achieved by this action.
Execute Setting- Confirms the setting change, if the change is valid then a positive response will be returned, if the setting change fails then an error response will be returned.
Abort Setting- This command can be used to abandon the setting change.
This is the most secure method and is ideally suited to on-line editors as the setting limits are taken from the relay before the setting change is made. However this method can be slow if many settings are being changed as three commands are required for each change.
1.4 Systems Integration Data
1.4.1 Address of the relay
The relays can have any address between 1 and 254 included. The address 255 corresponds to the global address to which all relays and all the other slave peripheries respond. The Courier protocol specifies that no response can be resent from the slave periphery to the global message. This permits to avoid that all peripheries respond at the same time creating by this way a conflict on the bus.
Each relay possesses an address settled on 255 in order to guarantee that in case of his connection to the operating network, his address cannot create any conflict with the address of another periphery already in exploitation. In order to permit to a new periphery to be entirely operational, his address has to be settled. The address can be modified manually in capturing the password, than in following the method of the setting change through the user interface on the front plate of the relay.
Technical Guide P92x/EN CT/I52 Courier Database MiCOM P921-P922-P923 Page 55/136
Similarly, if the computerized system used takes in charge the auto addressing, the relay address can be settled on 0 by activating the auto-addressing characteristics of the computer software. The relay receives then the next valid address on the bus.
If the address is 255 or not known, it can be modified by sending a new address, with a global message, to a periphery possessing a particular serial number. This method is used for those peripheries which do not have any user interface for reading or changing the address in process.
1.4.2 Measured Values
Each measured value can be periodically extracted by a selective call of MiCOM P921, P922 and P923 relays.
1.4.3 Status word
Each response of a slave periphery contains an octet of status. This octet is resent by the relay at the beginning of each message for signaling important data. The principal workstation can be designed to respond automatically to these important data.
The contained indications are the following:
Bit 0: 1=Recording of disturbance available for retrieval
Bit 1: 1=Change of the unit status word
Bit 2: 1=Change of the control status word
Bit 3: 1=Relay busy, no response possible in time
Bit 4: 1=Relay out of service
Bit 5: 1=Recording of events available for retrieval
Bit 6: 1=Switched Alarm indicator
Bit 7: 1=Switched tripping indicator
1.4.4 Unit Status word
The unit status word is located in the menu 000C
Each bits pair of the unit status word serves to indicate the status (position ) of the unit elements checked through the relay.
This functionality is not supported on MiCOM P921,P922 and P923 relays.
1.4.5 Control status word
The control status word is located in the cell of the menu 000D
It is used for transmitting the control information of the slave periphery to the central unit. Nevertheless, the relays described in this manual are protection relays , which do not use this control characteristic.
1.4.6 Logic input status word
The logical control input status can be observed in proceeding to a selective call from the cell of menu 0020. The 2 bits inferior of the returned value indicating the status of each of the 2 logic inputs. This cell is accessible only in reading.
Bit 0: Logic input 1
Bit 1: Logic input 2
Bit 2: Logic input 3
Bit 3: Logic input 4
Bit 4: Logic input 5

Bit 0: relay 1 (TRIP)
Bit 1,2,3: programmable relays n° 2,3,4,
Bit 4: Watchdog
Bit 5,6,7,8: programmable relays n° 5,6,7,8
1.4.8 Alarm Information
The status of internal controls triggered by the auto-control program of the relays can be observed in proceeding to a selective call of the cell of menu 0022.
The bits 0 to 6 indicate the material controls of the product.
Bit 0 Watchdog Error
Bit 1 Communication Error
Bit 2 Setting error
Bit 3 VT Error
Bit 4 Clock Error
Bit 5 Calibration error
Bit 6 Statistics Reset
Bit 9 Default settings.
1.4.9 Protection Indication
The protection indications provide the status of different protection elements in the relay; and thus the fault indications are so generated. In case of a fault recording, these indications are transmitted to an events recorder. This is the only way to access to these indications.
The status of the internal protection indication of the relays can be observed in proceeding to a selective call of the cell of menu 0023 , 0024, 0025 and 0026.
The next table presents the list of the protection indications of the cell 0023:

1.4.10 Control and supervision
The control functions through the relays can be executed using a serial link. These functions particularly constitute the changes of an individual relay setting parameters, the changes of the setting group, the remote control of the circuit breaker, as well as the functions and the locking of the selected output relays.
The remote control is limited to the selected control functions in the table of the relay menu. In order to modify this selection, a corresponding password is needed. The CRC and the controls of the message length are used every time a message is received . No response is given for message received with an error detection. The principle unit can be re-initialized in order to send again an order, as often as it seems necessary, if it does not receive any response or have received a response with an error detection.
NOTE: The control commands are generally materialized by the change of the cell value. They dispose the same inherent security. No response is allowed for the global orders to avoid any conflict in the bus. For this type of order, a double transmission is used by the relay for the verification of the message. The relay transmits then a confirmation indicating that the control order or the change of setting is accepted. If this is not the case, the relay sends an error message.
1.4.11 Remote Change of setting
When using the serial port, the relay responds to the orders of setting changes only if the SD0 Link =1 is selected.
• The selection of the SD0 Link =1 blocks all the remote changes of settings with the exception of the SC logical Links and the password capture.
• When the SD0 Link =0 is selected, the remote setting changes are protected by the password.
To make a remote changes of settings, a password is needed to be captured (remotely), and then the SD and SD0 function Links have to be set equal to 1.
1.5 Events Extraction (MiCOM P922 and P923 only)
Events can be extracted either manually or automatically. For automatic extraction all events are extracted in sequential order using the standard Courier mechanism, this includes Faults. The manual approach allows the user to select events and faults randomly from the stored records.
1.5.1 Automatic Event Extraction
This method is intended for continuous extraction of events and fault information as it is produced via the rear port.
When a new event information is created, the event bit is set within the status byte. This indicates to the Master device that an event information is available. The oldest (and not extracted ) event can be extracted from the relay using the Send Event Command. The relay will respond with the event data, which will be either a Courier Type 0 or Type 3 event. The latest type is used for the fault records.
Technical Guide P92x/EN CT/I52 Courier Database MiCOM P921-P922-P923 Page 59/136
Once an event is extracted from the relay, the Accept Event can be used to confirm that this event has been successfully extracted. If all the events are extracted, then the event bit will reset. If there are more events to be extracted, the next one can be accessed using the Send Event Command as before.
1.5.2 Events Types
Events will be created by the relay under the following circumstances:
• Change of state of output contact
• Change of state of opto input
• Protection element operation
• Alarm condition
• Setting change
• Fault record ( Type 3 Courier Event )
1.5.3 Event Format
The Send Event Command results in the return of the following fields by the relay:
• Cell Reference
• Time stamp
• Cell text
• Cell value
The list of events created by the relay (section 1.2.2) indicates how the content of the above mentioned fields are interpreted. The fault event will return a Courier Type 3 event which contains the above fields together with two additional fields:
• Event extraction column
• Event number
These fields contain additional information which are extracted from the relay using the referenced extraction column. Row 01 of the extraction column contains a setting which allows the selection of the fault record. This setting should be set to the event number value returned within the record, the extended data can be extracted from the relay by uploading the text and data from the column.
1.5.4 Manual record Extraction
Column 02 of the database can be used to manually view the fault records. The contents of this column will depend of the nature of the record selected. It is possible to select directly a fault record.
Fault record selection (Row 01) – this cell can be used to directly select a fault record using a value between 0 and 4 to select one of the five stored fault records (0 will be the most recent fault while 4 is the oldest one). The column will then contain the details of the fault record selected ( row 02 to 0A).
It should be noted that if this column is used to extract event information from the relay, the number associated with a particular record will change when a new fault occurs.
P92x/EN CT/I52 Technical Guide Courier Database Page 60/136 MiCOM P921-P922-P923
1.6 Disturbance Record Extraction
The stored disturbance records within the relay are accessible via the Courier interface.
Select Record Number (Row 01) – this cell can be used to select the record to be extracted. Record 0 will be the oldest un-extracted record, older records will be assigned positive values, and negative values will be used for more recent records. To facilitate automatic extraction via the rear port, the disturbance bit of the Status byte is set by the relay whenever there are un-extracted disturbance records.
Once a record has been selected, using the above cell, the time and date of the record can be read from the cell 02. The disturbance record itself can be extracted using the block transfer mechanism from cell B00B.
As it has been stated, the rear Courier port can be used to automatically extract disturbance records as they occur. This is possible when using the standard Courier mechanism defined in chapter 8 of the Courier User Guide.

1. IEC60870-5-103 INTERFACE
The IEC60870-5-103 interface is a master/slave interface with the relay as the slave device. This protocol is based on the VDEW communication protocol. The relay conforms to compatibility level 2, compatibility level 3 not supported.
The following IEC60870-5-103 facilities are supported by this interface:
• Initialization (Reset)
• Time synchronization
• Event Record Extraction
• General Interrogation
• Cyclic Measurements
• General Commands
1.1 Physical Connection and Link Layer
Connection is available for IEC60870-5-103 through the rear RS485 port. It is possible to select the relay address and baud rate using the front panel interface. Following a change, a reset command is required to re-establish communications.
The parameters of the communication are the following:
• Even Parity
• 8 Data bits
• 1 stop bit
• Data rate 9600 or 19200 bauds.
1.2 Initialization
Whenever the relay is powered up, or when the communication parameters are modified, a reset command is required to initialize the communications. The relay will respond to either of the two reset commands (Reset CU or Reset FCB), the difference being that the Reset CU will clear any message which is not sent in the relay’s transmit buffer.
The relay will respond to the reset command with an identification message ASDU5, the cause of transmission (COT) of this response will be either Reset CU or Reset FCB depending on the nature of the reset command. The following information will be contained in the data section of this ASDU:
Manufacturer Name: Schneider Electric
The Software Identification Section will contain the first four characters of the relay model number to identify the type of relay, e.g. P923.
In addition to the above identification message, if the relay has been powered up, it will also produce a power up event.
1.3 Time Synchronization (P922 & P923 only)
The relay time and date can be set using the time synchronization feature of the IEC60870-5-103 protocol. The relay will correct the transmission delay as specified in the IEC60870-5-103. If the time synchronization message is sent as a send/confirm message then the relay will respond with a confirm. If the time synchronization message is sent as a sent/confirm or broadcast (send/no reply) message, a time synchronization message will be returned as class 1 data.
P92x/EN CT/I52 Technical Guide IEC61870-5-103 Page 108/136 MiCOM P921-P922-P923
1.4 Spontaneous Events (P922 & P923 only)
The event created by the relay will be passed using the standard function type/information numbers to the IEC60870-5-103 master station. Private codes are not used, thus any event that can not pass using standardized messages will not be sent
Events are categorized using the following information:
• Common Address
• Function type
• Information number
Section 2 contains a complete listing of all events produced by the relay. The common address is used to differentiate in circumstances where the relay produces more events of a certain type than can be passed using the standardized messages. For example if the relay produces starts and trips for three stages of overcurrent only two stages can pass using the standardized messages.
Using the different common address for two of the overcurrent stages allows each stage to be indicated. The table in section2 shows the common address as an offset value. The common address offset will be added to the station address in order to pass these events.
1.5 General Interrogation
The GI request can be used to read the status of the relay. The function numbers, information numbers and common address offsets that will be returned during the GI cycle are indicated in Section 2.
1.6 Cyclic Measurements
The relay will produce measured value using ASDU 9 on a cyclic basis, this can be read from the relay using a class 2 poll ( note ASDU 3 is not used ).
It should be noted that the measurands transmitted by the relay are sent as a proportion of either 1.2 or 2.4 times the rated value of the analogue value. The selection of either 1.2 or 2.4 for a particular value is indicated in section 2.
1.7 Commands
A list of the supported commands is contained in section 2. The relay will respond to other commands with an ASDU 1, with a cause of transmission (COT) of negative acknowledgement of a command.
1.8 Disturbance Records (P922 & P923 only)
The disturbance records stored by the relay can be extracted using the mechanism defined in the IEC60870-5-103 standard. An ASDU 23 is transmitted at the end of each record creation.
1.9 Blocking of Monitor Direction
The relay support a facility to block messages in the Monitor direction (setting by HMI or communication protocol).
1.10 Blocking of Control Direction
The relay support a facility to block messages in the Control direction (setting by HMI or communication protocol).

2. IEC60870-5-103 DATABASE
2.1 IEC 60870-5-103 DATABASE
These messages include a sub-assembly of events which are generated on the relay, because some generated events are not registrated in IEC870-5-103. They are the most prioritary messages
An event is always generated on the rising edge of the information.
Some events can be generated on the rising or lowering edge.
In the list below, events only generated on rising edge will be tagged with a ‘*’.
Remark: Events in italic only exist for MICOM P922 and P923. Events in italic and bold only exist for MICOM P923.
2.1.1 List of Events produced by the relay
Two types of ASDU can be generated for events: ASDU 1 (time-tagged message) or ASDU 2 (time-tagged message with relative time).
The next processed events list is the list with the private option active, for all protection functions for Voltage and Frequency, with the associated FUNCTION Type, INFORMATION NUMBER, ASDU TYPE and CAUSE OF TRANSMISSION:
FUN <161>: Function type in Public range (compatible)
FUN <169>: Function type in Private range (Reserved for Voltage and Frequency Protections.

3. PROCESSED COMMANDS
3.1 System Commands
− Synchronization Command (ASDU 6):
FUN<255>, INF <0>, TYP <6>, COT<8>
This command can be sent to a specific relay, or global, it only exists on the P922 and P923. The time sent by master is the time of the first bit of the frame. The relay synchronizes with this time, corrected by the frame transmission delay. After updating its time, the relay send back an acknowledge to the master, by giving its new current time. This acknowledge message will be an event of ASDU 6 type.
− General Interrogation Initialization command (ASDU 7):
FUN<255>, INF <0>, TYP <7>, COT<9>
This command starts the relay interrogation:
The relay then sends a list of data containing the relay state (see list described above). The GI command contains a scan number which will be included in the answers of the GI cycle generated by the GI command.
If a data has just changed before extracted by the GI, the new state is sent to the master station.
When an event is generated during the GI cycle, the event is sent in priority, and the GI cycle is temporarily interrupted. The end of the GI consists in sending an ASDU 8 to the master station.
If, during a General Interrogation cycle, another GI Initialization command is received, the precedent answer is stopped, and the new GI cycle started.
3.2 General Commands (ASDU 20) (Control direction)
• Leds Reset: This command acknowledge all alarms on Front Panel : • FUN<161>,INF<19>, TYP<20>, COT <20> • Setting groupe number 1: FUN<161>,INF<23>, TYP<20>, COT <20> • Setting groupe number 2: FUN<161>,INF<24>, TYP<20>, COT <20> • Trip TC: FUN<169>,INF <1>; TYP <20>; COT<20> • Close TC: FUN<169>,INF <2>; TYP <20>; COT<20> • Unlock relays: FUN<169>,INF <231>; TYP <20>; COT<20> • General data reset: FUN<169>,INF <232>; TYP <20>; COT<20> • First alarm acknowledge: FUN<169>,INF <53>; TYP <20>; COT<20> • All alarms acknowledge: FUN<169>,INF <52>; TYP <20>; COT<20> • Communication Order 1: FUN<169>,INF <234>; TYP <20>; COT<20> • Communication Order 2: FUN<169>,INF <235>; TYP <20>; COT<20> • Communication Order 3: FUN<169>,INF <227>; TYP <20>; COT<20> • Communication Order 4: FUN<169>,INF <228>; TYP <20>; COT<20>
After executing one of these commands, the relay sends an acknowledge message, which contains the result of command execution.
If a state change is the consequence of the command, it must be sent in a ASDU 1 with COT 12 (remote operation).
If the relay receive another command message from the master station before sending the acknowledge message, it will be discarded.
Commands which are not processed by the relay are rejected with a negative acknowledge message.

4. RELAY RE-INITIALIZATION
In case of relay re-initialization, the relay send to the master station:
− A message indicating relay start (FUN<161>,INF <5>; TYP <5> COT <6>)
− or a message indicating Reset CU (FUN<161>,INF <5>; TYP <3> COT <4>)
− or a message indicating Reset FCB (FUN<161>,INF <5>; TYP <2> COT <3>)
− Each identification message of the relay (ASDU 5) contains the manufacturer name in 8 ASCII characters and. 4 characters including: 921 or 922 or 923 in numeric in the first 2 characters, to describe the protection, and the release number in the 2 last characters, for example 62 in the lower and 0 in the higher for release “6.C” (“C” is equivalent to 2).
5. CYCLIC MESSAGES (ASDU 9 AND ASDU 77)
Only measurands can be stored in these messages.
The measurands values are stored in lower levels of communication, before polling by master station.
Several of the fields in the ASDU 9 (FUN<161>, INF <148>) are unused in the P921/P922/P923 relay (Current and Power values), so they are set to 0: Only RMS Ua, Ub, Uc values and frequency are stored (with a rate such as: 2,4 * nominal value = 4096).
The second ASDU is ASDU3.4 (FUN<161>, INF<147>), which contains in second position Vn earth voltage value in rated format (with a rate such as: 2,4 * nominal value = 4096). In value does not exist, so the first position value in ASDU3.4 is set to « unused «.
Another ASDU, ASDU 77 (FUN<169>, INF <209>), which is a private ASDU, contains 6 other measurands (Only P922/P923): V1 (V direct) and V2 (V inverse) values, and Uab module, Ubc module, Uca module, V0 module values, in Volts, and in «short floating-point » format (IEEE 32 bits floating-point format). These values are not rated.
6. IEC870-5-103 MESSAGES FOR DISTURBANCE RECORD EXTRACTION (ONLY P922/923)
Only measurands can be stored in these messages.
The disturbance extraction procedure with IEC870-5-103 in MICOM Px2x relays is in conformance with IEC870-5-103 standard definition.
The maximum disturbance record number stored in a P922/P923 is 5.
The disturbance record mapping for P922 and P923 is the following:
− Number of analog channels transmitted: 4, which are:
• Channel 1: Ua current (Phase L1). • Channel 2: Ub current (Phase L2). • Channel 3: Uc current (Phase L3). • Channel 4: Vn current (Earth).
− Identifiers of tags (14) transmitted in ASDU 29 (logical informations) for P922 or P923:
• Tag number 1: VN>: FUN <169> INF <67> • Tag number 2: General start: FUN <161> INF <84> • Tag number 3: General Trip: FUN <161> INF <68> • Tag number 4: tU>: FUN <169> INF <90> • Tag number 5: tU>>: FUN <169> INF <91>

7. IEC870-5-103 FAULT DATA RECORD EXTRACTION (ONLY P922/923)
The fault data are extracted with IEC870-5-103 in MICOM Px2x relays in conformance with AREVA IEC870-5-103 private definitions described in document: MiCOMACAPart4_IEC60870-5-103_G. These data are uploaded through ASDU 4 messages, containing the following values in IEEE 32 bits floating-point format, at the end of disturbance record upload, before the acknowledgement of the record:
− fault number: FUN <243> INF <1> − active group (1 to 2): FUN <243> INF <2> − phase origin (F1x): FUN <243> INF <3> − fault code (F109): FUN <243> INF <4> − fault magnitude: FUN <243> INF <5> − fault Va magnitude (unit= V): FUN <243> INF <6> − fault Vb magnitude (unit= V): FUN <243> INF <7> − fault Vc magnitude (unit= V): FUN <243> INF <8> − fault Vn magnitude (unit= V): FUN <243> INF <9> Format F1x: 0: None, 1: Phase A, 2: Phase B, 3: Phase C, 4: Phase AB, 5: Phase AC, 6: Phase BC, 7: Phase A B C, 8: Earth

2. DNP V3.00 DEVICE PROFILE
The next table provides a “Device Profile Document” in the standard format defined in the DNP 3.0 Subset Definitions Document. While it is referred to in the DNP 3.0 Subset Definitions as a “Document,” it is only a component of a total interoperability guide. This table, in combination with the following should provide a complete interoperability/configuration guide:
− the Implementation Table (section 3, page 124),
− the Point List Tables (section 4, page 128),

Note 1: A Default variation refers to the variation responded when variation 0 is
requested and/or in class 0, 1, 2, or 3 scans. Note 2: For static (non-change-event) objects, qualifiers 17 or 28 are only
responded when a request is sent with qualifiers 17 or 28, respectively. Otherwise, static object requests sent with qualifiers 00, 01, 06, 07, or 08, will be responded with qualifiers 00 or 01. (For change-event objects, qualifiers 17 or 28 are always responded.)
Note 3: For MiCOM P92x relays, a cold restart is implemented as a warm restart – the executable is not restarted, but the DNP process is restarted.

4.4 Analog Inputs
The next table lists Analog Inputs (Object 30). It is important to note that 16-bit and 32-bit variations of Analog Inputs, Analog Output Control Blocks, and Analog Output Statuses are transmitted through DNP as signed numbers. Even for analog input points that are not valid as negative values, the maximum positive representation is 32767. For each point, the “Scaling and Units” column indicates the value of a transmitted 32767. This also implies the value of a transmitted –32767. The entry in the column does not imply a valid value for the point.
Always indicating the representation of 32767 in the tables below is a consistent method for representing scale, applicable to all scaling possibilities.
The “Default Deadband,” and the “Default Change Event Assigned Class” columns are used to represent the absolute amount by which the point must change before an analog change event will be generated, and once generated in which class poll (1, 2, 3) will the change event be reported. Only the default values for these columns are documented here because the values may change in operation due to either local (user-interface) or remote (through DNP) control.
Analog Inputs points are included in class 0 polls, because they are included in one of classes 1, 2 or 3.

1. RECEIPT OF RELAYS
Protective relays, although generally of robust construction, require careful treatment prior to installation on site. Upon receipt, relays should be examined immediately to ensure no external damage has been sustained in transit. If damage has been sustained, a claim should be made to the transport contractor and Schneider Electric should be promptly notified.
Relays that are supplied unmounted and not intended for immediate installation should be returned to their protective polythene bags and delivery carton. Section 3 of this chapter gives more information about the storage of relays.
P92x/EN IN/I52 Technical Guide Installation Page 4/12 MiCOM P921/P922 & P923
2. HANDLING OF ELECTRONIC EQUIPMENT
A person’s normal movements can easily generate electrostatic potentials of several thousand volts. Discharge of these voltages into semiconductor devices when handling electronic circuits can cause serious damage which, although not always immediately apparent, will reduce the reliability of the circuit. This is particularly important to consider where the circuits use complementary metal oxide semiconductors (CMOS), as is the case with these relays.
The relay’s electronic circuits are protected from electrostatic discharge when housed in the case. Do not expose them to risk by removing the front panel or printed circuit boards unnecessarily.
Each printed circuit board incorporates the highest practicable protection for it’s semiconductor devices. However, if it becomes necessary to remove a printed circuit board, the following precautions should be taken to preserve the high reliability and long life for which the relay has been designed and manufactured.
1.
2.
3.
4.
5.
Before removing a printed circuit board, ensure that you are at the same electrostatic potential as the equipment by touching the case.
Handle analogue input modules by the front panel, frame or edges of the circuit boards. Printed circuit boards should only be handled by their edges. Avoid touching the electronic components, printed circuit tracks or connectors.
Do not pass the module to another person without first ensuring you are both at the same electrostatic potential. Shaking hands achieves equipotential.
Place the module on an anti-static surface, or on a conducting surface which is at the same potential as yourself.
If it is necessary to store or transport printed circuit boards removed from the case, place them individually in electrically conducting anti-static bags.
In the unlikely event that you are making measurements on the internal electronic circuitry of a relay in service, it is preferable that you are earthed to the case with a conductive wrist strap. Wrist straps should have a resistance to ground between 500kΩ to 10MΩ. If a wrist strap is not available you should maintain regular contact with the case to prevent a build-up of electrostatic potential. Instrumentation which may be used for making measurements should also be earthed to the case whenever possible.
More information on safe working procedures for all electronic equipment can be found in BS EN 100015:Part 1:1992. It is strongly recommended that detailed investigations on electronic circuitry or modification work should be carried out in a special handling area such as described in the aforementioned British Standard document.
Technical Guide P92x/EN IN/I52 Installation MiCOM P921/P922 & P923 Page 5/12
3. STORAGE
If relays are not to be installed immediately upon receipt, they should be stored in a place free from dust and moisture in their original cartons. Where de-humidifier bags have been included in the packing they should be retained.
The action of the de-humidifier crystals will be impaired if the bag is exposed to ambient conditions and may be restored by gently heating the bag for about an hour prior to replacing it in the carton. Care should be taken on subsequent unpacking that any dust which has collected on the carton does not fall inside. In locations of high humidity the carton and packing may become impregnated with moisture and the de-humidifier crystals will lose their efficiency.
Prior to installation, relays should be stored at a temperature of between –25° to +70°C.
Sustained exposure to high humidity during storage may cause damage to electronics and reduce the lifetime of the equipment.
Therefore, once the MiCOM products have been unpacked, we recommend that they are energized within the three following months.
Where electrical equipment is being installed, sufficient time should be allowed for acclimatisation to the ambient temperature of the environment, before energisation.
P92x/EN IN/I52 Technical Guide Installation Page 6/12 MiCOM P921/P922 & P923
4. UNPACKING
Care must be taken when unpacking and installing the relays so that none of the parts are damaged and additional components are not accidentally left in the packing or lost.
Relays must only be handled by skilled persons.
The site should be well lit to facilitate inspection, clean, dry and reasonably free from dust and excessive vibration. This particularly applies to installations which are being carried out at the same time as construction work.
Technical Guide P92x/EN IN/I52 Installation MiCOM P921/P922 & P923 Page 7/12
5. RELAY MOUNTING
MiCOM relays are dispatched either individually or as part of a panel/rack assembly.
Individual relays are normally supplied with an outline diagram showing the dimensions for panel cut-outs and hole centres. This information can also be found in the product publication.
Secondary front covers can also be supplied as an option item to prevent unauthorised changing of settings and alarm status. They can be ordered under the reference GEN0055 (size 20TE).
The design of the relay is such that the fixing holes in the mounting flanges are only accessible when the access top and bottom covers are open and hidden from sight when the covers are closed.
If an MMLG test block is to be included, it is recommended that, when viewed from the front, it is positioned on the right-hand side of the relay (or relays) with which it is associated. This minimises the wiring between the relay and test block, and allows the correct test block to be easily identified during commissioning and maintenance tests.
5.1 Rack Mounting
MiCOM relays may be rack mounted using single tier rack frames (our part number FX0021 001), as illustrated in Figure 1. These frames have been designed to have dimensions in accordance with IEC60297 and are supplied pre-assembled ready to use. On a standard 483 mm rack system this enables combinations of widths of case up to a total equivalent of size 80TE to be mounted side by side.
The two horizontal rails of the rack frame have holes drilled at approximately 26 mm intervals and the relays are attached via their mounting flanges using No.4 recessed head self-tapping screws.
Once the tier is complete, the frames are fastened into the racks using mounting angles at each end of the tier.
P0403XXb
FIGURE 1: RACK MOUNTING OF RELAYS
P92x/EN IN/I52 Technical Guide Installation Page 8/12 MiCOM P921/P922 & P923
Relays can be mechanically grouped into single tier (4U) or multi-tier arrangements by means of the rack frame. This enables schemes using products from the MiCOM and MiDOS product ranges to be pre-wired together prior to mounting.
Where the case size summation is less than 80TE on any tier, or space is to be left for installation of future relays, blanking plates may be used. These plates can also be used to mount ancillary components. Figure 1 shows the sizes that can be ordered.
NOTE: Blanking plates are only available in black.
Further details on mounting MiDOS relays can be found in publication R7012, “MiDOS Parts Catalogue and Assembly Instructions”.

5.2 Panel Mounting
The relays can be flush mounted into panels using self-tapping screws passing through the front mounting flanges. Alternatively tapped holes can be used if the panel has a minimum thickness of 2.5 mm.
For applications where relays need to be semi-projection or projection mounted, a range of collars are available. Further details can be obtained from the Contracts Department of Schneider Electric.
Where several relays are to mounted in a single cut-out in the panel, it is advised that they are mechanically grouped together horizontally and/or vertically to form rigid assemblies prior to mounting in the panel.
NOTE: It is not advised that MiCOM relays are fastened using pop rivets as this will not allow the relay to be easily removed from the panel in the future if repair is necessary.
If it is required to mount a relay assembly on a panel complying to BS EN60529 IP52, it will be necessary to fit a metallic sealing strip between adjoining relays (Part no GN2044 001) and a sealing ring selected from Table 2 around the complete assembly.

7. RELAY WIRING
This section serves as a guide to selecting the appropriate cable and connector type for each terminal on the MiCOM relay.
Before carrying out any work on the equipment the user should be familiar with the contents of the Safety Section/Safety Guide SFTY/4LM/D11 or later issue and the ratings on the equipment’s rating label.
7.1 Medium and Heavy Duty Terminal Block Connections
Loose relays are supplied with sufficient M4 screws for making connections to the rear mounted terminal blocks using ring terminals, with a recommended maximum of two ring terminals per relay terminal.
If required, Schneider Electric can supply M4 90° crimp ring terminals in five different sizes depending on wire size (see Table 3 and Table 4). Each type is available in bags of 100.

TABLE 4: M4 CRIMP RING TERMINALS
* To maintain the terminal block insulation requirements for safety, an insulating sleeve should be fitted over the ring terminal after crimping.
The following minimum wire sizes are recommended:
− Auxiliary Supply, Vx 1.5 mm2
− RS485 port See separate section
− Other circuits 1.0 mm2
P92x/EN IN/I52 Technical Guide Installation Page 12/12 MiCOM P921/P922 & P923
Due to the limitations of the ring terminal, the maximum wire size that can be used for any of the medium or heavy duty terminals is 6.0 mm2 using ring terminals that are not pre-insulated. Where it required to only use pre-insulated ring terminals, the maximum wire size that can be used is reduced to 2.63 mm2 per ring terminal. If a larger wire size is required, two wires should be used in parallel, each terminated in a separate ring terminal at the relay.
The wire used for all connections to the medium and heavy duty terminal blocks, except the RS485 port, should have a minimum voltage rating of 300Vrms.
It is recommended that the auxiliary supply wiring should be protected by a 16A high rupture capacity (HRC) fuse of type NIT or TIA. For safety reasons, current transformer circuits must never be fused. Other circuits should be appropriately fused to protect the wire used.
7.2 RS485 Port
Connections to the RS485 port are made using ring terminals. It is recommended that a 2 core screened cable is used with a maximum total length of 1000m or 200nF total cable capacitance.
A typical cable specification would be:
− Each core: 16/0.2 mm copper conductors PVC insulated
− Nominal size: 0.5 mm2 per core
− Screen: Overall braid, PVC sheathed
Refer to chapter P92x/EN CO, paragraph 2.2 for references of RS232/RS485 converters.
7.3 Protective Conductor (Earth) Connection
Every relay must be connected to the local earth bar using the M4 earth studs in the bottom left hand corner of the relay case. The minimum recommended wire size is 2.5 mm2 and should have a ring terminal at the relay end. Due to the limitations of the ring terminal, the maximum wire size that can be used for any of the medium or heavy duty terminals is 6.0 mm2 per wire. If a greater cross-sectional area is required, two parallel connected wires, each terminated in a separate ring terminal at the relay, or a metal earth bar could be used.
NOTE: To prevent any possibility of electrolytic action between brass or copper earth conductors and the rear panel of the relay, precautions should be taken to isolate them from one another. This could be achieved in a number of ways, including placing a nickel-plated or insulating washer between the conductor and the relay case, or using tinned ring terminals.

1. INTRODUCTION
The MiCOM P921-P922-P923 protection relays are fully numerical in their design, implementing many protection and non-protection functions. The relays periodically conduct self-checking and, in the unlikely event of a failure, will trigger an alarm. As a result of this, the commissioning tests do not need to be as extensive as with non-numeric electronic or electro-mechanical relays.
To commission numeric relays, it is only necessary to verify that the hardware is functioning correctly and the application-specific software settings have been applied to the relay. It is considered unnecessary to test every function of the relay if the settings have been verified by one of the following methods:
• Extracting the settings applied to the MiCOM relay using appropriate setting software (Preferred method)
• Via the operator interface
To confirm that the product is operating correctly once the application-specific settings have been applied, a test should be performed on a single protection element.
Unless previously agreed to the contrary, the customer will be responsible for determining the application-specific settings to be applied to the relay.
Blank commissioning test and setting records are provided in chapter P92x/EN RS for completion as required.
The commissioning tests must always be performed in conformity with the rules and regulations of the country of use.
Before carrying out any work on the equipment the user should be familiar with the contents of the Safety Section/Safety Guide SFTY/4LM/D11 or later issue and the ratings on the equipment’s rating label.
P92x/EN CM/I52 Techncal Guide Commissioning Guide Page 4/26 MiCOM P921/P922 & P923
2. SETTING FAMILIARISATION
When commissioning a MiCOM P921, P922 or P923 relay for the first time, sufficient time should be allowed to become familiar with various menus containing the settings.
The “User Guide” section (Chapter P92x/EN FT) of this technical guide gives a detailed description of the menu structures for the MiCOM P921, P922 and P923 relays.
With the plastic front cover in place all keys except the key are accessible. All menu cells can be read. LEDs and alarms can be reset. However, no protection or configuration settings can be changed.
Removing the cover allows access to all keys so that settings can be changed. However, certain settings with protected access will require the appropriate password to be entered before changes can be made.
Alternatively, if a portable PC is available together with suitable setting software (such as MiCOM S1), the settings can be viewed a page at a time and printed. This software also allows settings to be entered more easily, saved to a file on disk for future reference or printed to produce a setting record.
Technical Guide P92x/EN CM/I52 Commissioning Guide MiCOM P921/P922 & P923 Page 5/26
3. EQUIPMENT REQUIRED FOR COMMISSIONING
3.1 Minimum equipment required
Voltmeter test set with chronometer (range: 0 to 240 VAC).
Supply voltage of 48-125 VDC or 220 VAC.
Multimeter with suitable AC current range, and AC/DC voltage ranges of 0 - 250V respectively.
Continuity tester (if not included in multimeter)
Phasemeter.
Indicates the order of succession of phases.
NOTE: Modern test equipment may contain many of the above features in one unit.
3.2 Optional equipment
Multi-finger test plug type MMLB01 (if test block type MMLG installed).
An electronic or brushless insulation tester with a dc output not exceeding 500V (for insulation resistance testing when required).
A portable PC, with appropriate software (this enables the rear communications port to be tested, if this is to be used, and will also save considerable time during commissioning).
KITZ K-Bus to RS232 protocol converter (if RS485 K-Bus port is being tested and one is not already installed).
RS485 to RS232 converter (if RS485 Modbus port is being tested). Part numbers RS-CONV1 or RS-CONV32 (please contact us for more information).
A printer (for printing a setting record from the portable PC).
P92x/EN CM/I52 Techncal Guide Commissioning Guide Page 6/26 MiCOM P921/P922 & P923
4. PRODUCT CHECKS
These product checks cover all aspects of the relay which should be checked to ensure that it has not been physically damaged prior to commissioning, is functioning correctly and all input quantity measurements are within the stated tolerances.
If the application-specific settings have been downloaded to the relay prior to commissioning, it is advisable to make a copy of the settings so as to allow their restoration later. To do this use one of the methods described below:
• Obtain a setting file on a diskette from the customer (this requires a portable PC with appropriate setting software, e.g. MiCOM S1).
• Extract the settings from the relay itself (this again requires a portable PC with appropriate setting software).
• Manually create a setting record. This can be done using a copy of the setting record located in chapter P92x/EN RS to record the settings as the relay’s menu is sequentially stepped through via the front panel user interface.
If password protection is enabled and the customer has changed the password to prevent changes to some of the settings, either the revised password should be provided, or the customer should restore the original password prior to commencement of testing.
NOTE: In the event that the password has been lost, a recovery password can be obtained from Schneider Electric by quoting the serial number of the relay.
4.1 With the relay de-energised
THE FOLLOWING GROUP OF TESTS SHOULD BE CARRIED OUT WITHOUT THE AUXILIARY SUPPLY CONNECTED TO THE RELAY AND WITH THE TRIP CIRCUIT ISOLATED.
The voltage transformer connections must be isolated from the relay for these checks. If an MMLG test block is provided, the required isolation can easily be achieved by inserting test plug type MMLB01 which effectively open-circuits all wiring routed through the test block.
Before inserting the test plug, reference should be made to the scheme (wiring) diagram to ensure that this will not potentially cause damage or a safety hazard.
If a test block is not provided, the voltage transformer supply to the relay should be isolated by means of the panel links or connecting blocks. Where means of isolating the auxiliary supply and trip circuit (e.g. isolation links, fuses, MCB, etc.) are provided, these should be used. If this is not possible, the wiring to these circuits will have to be disconnected and the exposed ends suitably terminated to prevent them from being a safety hazard.
Technical Guide P92x/EN CM/I52 Commissioning Guide MiCOM P921/P922 & P923 Page 7/26
4.1.1 Visual inspection
Carefully examine the relay to see that no physical damage has occurred since installation.
The rating information given under the top cover on the front of the relay should be checked to ensure it is correct for the particular installation.
Ensure that the case protective conductor terminal upper right-hand corner at the rear of the relay case, is used to connect the relay to a local earth bar using an adequate conductor, minimum size 1.5mm2.
P0386XXa
FIGURE 1: REAR TERMINAL BLOCKS ON SIZE 20TE CASE
4.1.2 Insulation
Insulation resistance tests are only necessary during commissioning if it is required for them to be done and they haven’t been performed during installation.
Isolate all wiring from the earth and test the insulation with an electronic insulation tester at a DC voltage not exceeding 500V. Terminals of the same circuits should be temporarily connected together.
The main groups of relay terminals are:
a) Voltage transformer circuits.
b) Auxiliary voltage supply.
c) External voltage output and opto-isolated inputs.
d) Relay contacts.
e) RS485 communication port.
f) Case earth.
The insulation resistance should be greater than 100MΩ at 500V.
P92x/EN CM/I52 Techncal Guide Commissioning Guide Page 8/26 MiCOM P921/P922 & P923
4.1.3 On completion of the insulation resistance tests, ensure all external wiring is correctly reconnected to the relay.
4.1.4 External wiring
Check that the external wiring is correct to the relevant connection diagram or scheme diagram.
If an MMLG test block is provided, the connections should be checked against the scheme (wiring) diagram. It is recommended that the supply connections are to the live side of the test block (coloured orange with the odd numbered terminals (1, 3, 5, 7 etc.)). The auxiliary supply is normally routed via terminals 13 (supply positive) and 15 (supply negative), with terminals 14 and 16 connected to the relay’s positive and negative auxiliary supply terminals respectively. However, check the wiring against the schematic diagram for the installation to ensure compliance with the customer’s normal practice.
4.1.5 Watchdog contacts
Using a continuity tester, check that the normally closed watchdog contacts are in the states given in Table 1 for a de-energised relay.

36-37 Open Closed
TABLE 1: WATCHDOG CONTACT STATUS
Technical Guide P92x/EN CM/I52 Commissioning Guide MiCOM P921/P922 & P923 Page 9/26
4.1.6 Auxiliary supply
The relay can be operated from either a DC only or an AC/DC auxiliary supply depending on the relay’s nominal supply rating. The voltage must be within the operating range specified in Table 2.
Without energising the relay, measure the auxiliary supply to ensure it is within the operating range.
Nominal supply rating
DC [AC RMS]
DC operating range
AC operating range
24-60 Vdc [-] 19 to 72 V -

[100/250 V] 104 to 300 V 88 to 300 V
TABLE 2: OPERATIONAL RANGE OF AUXILIARY SUPPLY
It should be noted that the relay can withstand an AC ripple of up to 12 % of the upper rated voltage on the DC auxiliary supply.
DO NOT ENERGISE THE RELAY USING THE BATTERY CHARGER WITH THE BATTERY DISCONNECTED AS THIS CAN IRREPARABLY DAMAGE THE RELAY'S POWER SUPPLY CIRCUITRY
ENERGISE THE RELAY IF THE AUXILIARY SUPPLY IS WITHIN THE OPERATING RANGE. IF AN MMLG TEST BLOCK IS PROVIDED, IT MAY BE NECESSARY TO LINK ACROSS THE FRONT OF THE TEST PLUG TO CONNECT THE AUXILIARY SUPPLY TO THE RELAY.
4.2 With the relay energised
THE FOLLOWING GROUP OF TESTS VERIFY THAT THE RELAY HARDWARE AND SOFTWARE IS FUNCTIONING CORRECTLY AND SHOULD BE CARRIED OUT WITH THE AUXILIARY SUPPLY APPLIED TO THE RELAY.
THE VOLTAGE TRANSFORMER CONNECTIONS MUST REMAIN ISOLATED FROM THE RELAY FOR THESE CHECKS.
4.2.1 Watchdog contacts
Using a continuity tester, check the watchdog contacts are in the states given in Table 1 for an energised relay.
4.2.2 Date and time
Set the date and time to the correct values. Refer to Chapter P92x/EN FT of the Technical guide.
P92x/EN CM/I52 Techncal Guide Commissioning Guide Page 10/26 MiCOM P921/P922 & P923
4.2.3 Light Emitting Diodes (LEDs)
On power up the green LED should have illuminated and stayed on indicating that the relay is healthy. The relay has non-volatile memory which remembers the state (on or off) of the alarm and trip LEDs when the relay was last energised from an auxiliary supply. Therefore these indicators may also illuminate when the auxiliary supply is applied.
If any of these LEDs are on then they should be reset before proceeding with further testing. If the LEDs successfully reset (the LED goes out), there is no testing required for that LED because it is known to be operational.
4.2.3.1 Testing the alarm LED
To do this, activate the "Undervoltage" function, 1st stage.
If there is no voltage across the VT inputs, the "alarm" LED begins to flash and a message appears on the front panel.
4.2.3.2 Testing the trip LED
Repeat the previous test and allocate the time-delayed information (tV<) to the trip relay. Check that the trip LED has illuminated.
4.2.3.3 Testing the user-programmable LEDs
Repeat the previous test and allocate the instantaneous information (V<) to LED 5, then to LEDs 6, 7 and 8. Check that each LED has illuminated.
4.2.4 Opto-isolated inputs
This test checks that all the opto-isolated inputs on the relay are functioning correctly. (2 opto-isolated inputs for the P921 and 5 opto-isolated inputs for the P922 and P923).
The opto-isolated inputs should be energised one at a time. Ensuring correct polarity, connect the auxiliary voltage to the appropriate terminals for the input being tested. The opto-isolated input terminal allocations are given in Table 3.
The line "INPUTS" in the "OP. PARAMETERS" menu gives the state of each input, a '1' indicating an energised input and a '0' indicating a de-energised input. When each input is energised one of the digits on the bottom line of the display will change to the value shown in Table 3 to indicate the new state of the inputs.

4.2.5 Output relays
This test checks that all the output relays are functioning correctly. (4 output relays for the P921 and 8 output relays for the P922-P923).
The output relays should be energised one at a time.
Connect a continuity tester across the terminals corresponding to output relay 1 given in Table 4.
To actuate each output relay, activate the "Undervoltage" function, 1st stage.
Allocate the instantaneous information (V<) to the relay to be tested; for example, enter the following settings in the "OUTPUTS" sub-menu of the "CONTROL SYSTEMS" menu:
V< 8 7 6 5 4 3 2
0 0 0 0 0 0 1
to control relay no. 2.
Repeat the test for each relay, modifying the allocation of the instantaneous information (V<).
To validate relay RL1 (trip relay), allocate the time-delayed information (tV<) to the relay in the "CONF DEC" sub-menu of the "CONTROL SYSTEMS" menu.
Operation will be confirmed by the continuity tester operating for a normally open contact and ceasing to operate for a normally closed contact.
NOTE: It should be ensured that thermal ratings of anything connected to the output relays during the test procedure is not exceeded by the associated output relay being operated for too long. It is therefore advised that the time between application and removal of relay testing is kept to the minimum.

4.2.6 Rear communications port
This test should only be performed where the relay is to be accessed from a remote location and will vary depending on the communications standard being adopted.
It is not the intention of the test to verify the operation of the complete system from the relay to the remote control centre, just the relay's rear communications port and any protocol converter necessary.
The protocol available for remote communication appears on the label on the relay front panel (under the top cover).
4.2.6.1 Courier communications
If a K-Bus to RS232 KITZ protocol converter is installed, connect a portable PC running the appropriate software to the incoming (remote from relay) side of the protocol converter.
If a KITZ protocol converter is not installed, it may not be possible to connect the PC to the type installed. In this case a KITZ protocol converter and portable PC running appropriate software should be temporarily connected to the relay’s K-Bus port. The terminal numbers for the relay’s K-Bus port are given in Table 5. However, as the installed protocol converter is not being used in the test, only the correct operation of the relay’s K-Bus port will be confirmed.

4.2.6.2 Modbus communications
Connect a portable PC (“master station”) running the appropriate Modbus Master Station software to the relay’s RS485 port via a RS485 to RS232 interface converter. The terminal numbers for the relay’s RS485 port are given in Table 5.
Ensure that the relay address, baud rate and parity settings in the Modbus software are set the same as on the MiCOM relay (see "COMMUNICATIONS" menu).
Check that communications with this relay can be established.
4.2.6.3 IEC60870-5-103 (VDEW) communications
IEC60870-5-103/VDEW communication systems are designed to have a local Master Station. This should be used to verify that the relay's fibre optic or RS485 port, as appropriate, is working.
Ensure that the relay address, baud rate and parity settings in the Master Station software are set the same as on the MiCOM relay (see "COMMUNICATIONS" menu).
Check that, using the Master Station, communications with the relay can be established.

4.2.7 Voltage inputs
This test verifies the accuracy of voltage measurement is within the acceptable tolerances.
4 types of connection are possible for the MiCOM P921, P922 and P923 relays: 3VT (phase-neutral), 3VT (phase-phase) + residual VT, 3VT (phase-neutral) + residual VT, 2VT (phase-phase) + residual VT.
THE FOLLOWING TESTS ARE PERFORMED WITH A 3VT CONNECTION (PHASE-PHASE) CORRESPONDING TO THE MOST FREQUENT CONFIGURATION.
Apply the rated voltage to each voltage input. Check its magnitude using a multimeter. Refer to Table 6 for the corresponding reading in the relay's "MEASUREMENTS" menu and record the value displayed.

The measured voltage values on the relay will be in primary volts.
The measurement accuracy of the relay is ±1%. Nevertheless, additional allowance must be made for the accuracy of the test equipment being used.
P92x/EN CM/I52 Techncal Guide Commissioning Guide Page 14/26 MiCOM P921/P922 & P923
5. SETTING CHECKS
The setting checks ensure that all of the relay settings (i.e. the relay’s protection and control settings and programmable logic equations) for the particular installation have been correctly applied to the relay.
5.1 Applying the settings to the relay
There are two methods of applying the settings:
• Transfer them from a pre-prepared setting file to the relay using a portable PC running the appropriate software via the relay’s front RS232 port, located under the bottom cover, or via the rear communications port. This method is preferred for transferring function settings as it is much faster and there is less margin for error.
NOTE: If a setting file has been created for the particular application and provided on a diskette, this will further reduce the commissioning time.
• Enter them manually via the relay’s operator interface.
5.2 Checking the relay settings
The settings applied to the relay should be carefully checked to ensure they have been entered correctly.
There are two methods of checking the settings:
• Extract the settings from the relay using a portable PC running the appropriate software via the front RS232 port, located under the bottom cover, or via the rear communications port:
− with a KITZ protocol converter connected if the rear protocol is Kbus,
− with a standard RS232/RS485 converter if the rear protocol is Modbus.
• Compare the settings taken from the relay with the original application-specific settings (for cases where the customer has only provided a printed copy of the required settings but a portable PC is available).
• Step through the settings using the relay's operator interface and compare them with the original settings.

5.3.3 Configuration with 3 single voltages (“3Vpn”) and “AND” detection logic
Do not exceed a maximum voltage of 2xVn in the following tests.
In view of the detection logic (“AND”), the voltages must be injected into the 3 phase inputs to cause tripping to occur.
5.3.3.1 Stages (V>) or (V<) with definite time delay
Values to be measured:
1.
2.
stage (V>) or (V<)
time delay (tV>) or (tV<)
Stage (V>) check:
1.
2.
3.
If time delay (tV>) is short, gradually inject the voltage into the 3 phases up to the stage value: tripping should occur for a voltage equal to the stage (V>) to within ±2%
If time delay (tV>) is long, inject a voltage equal to 0.98x(V>) into the 3 phases and check that tripping does not occur. Then inject 1.2x(V>) and check that tripping occurs.
Gradually reduce the voltage on one of the phases and measure the value of the drop-off stage (V>): the function must reset for a voltage less than or equal to the programmed hysteresis.
Stage (V<) check:
1. If time delay (tV<) is short, gradually reduce the voltage on the 3 phases from the rated voltage to the stage value: tripping should occur for a voltage equal to the stage (V<) to within ±2%
2. If time delay (tV<) is long, inject a voltage equal to 1.02x(V<) into the 3 phases and check that tripping does not occur. Then inject 0.8x(V<) and check that tripping occurs.
3. Gradually increase the voltage on one of the phases and measure the value of the drop-off stage (V<): the function must reset for a voltage greater than or equal to 1.02x(V<).
Action check:
1. appearance of an alarm message on the display
2. flashing of the “Alarm” LED
3. illumination of the “Trip” LED if tripping is programmed
4. illumination of the LEDs associated with instantaneous information (V>) and (V<) and time-delayed information (tV>) and (tV<) if programmed
5. trip relay operation (RL1) if programmed
6. operation of output relay associated with stages (V>) and (V<) if programmed
P92x/EN CM/I52 Techncal Guide Commissioning Guide Page 18/26 MiCOM P921/P922 & P923
Time delay (tV>) check:
1. Preset the injection voltage to a value equal to 2x(V>).
2. Inject the voltage into the 3 phases simultaneously.
3. Measure the time delay (tV>): it must be equal to the parametered value ±2% (or a minimum of ±20ms).
Time delay (tV<) check:
1. Disconnect the previously injected voltage.
2. Measure the time delay (tV<): it must be equal to the parametered value ±2% (or a minimum of ±20ms).
5.3.3.2 Stages (V>) or (V<) with inverse time delay
Values to be measured: time delays (tV>) and (tV<)
Action check: see above.
Time delays (tV>) and (tV<) check:
The time delay is measured for two injected voltages, for example at 1.1x(V>) and 1.4x(V>).
Injected voltage Rated trip time for TMS=1 (in seconds)
1.2x(U>) 5
1.4x(U>) 2.5
The time delay measured must be equal to the parametered value ±5% (or a minimum of ±40ms).
The time delay is measured for two injected voltages, for example at 0.9x(V<) and 0.6x(V<).
Injected voltage Rated trip time for TMS=1 (in seconds)
0.9x(V<) 10
0.6x(U<) 2.5
The time delay measured must be equal to the parametered value ±5% (or a minimum of ±40ms).
5.3.4 Configuration with 3 single voltages (“3Vpn”) and “OR” detection logic
Repeat the tests described in paragraph 5.3.3, injecting the voltage into one phase only. In view of the detection logic (“OR”), tripping should occur in these conditions.

∗ Delete as appropriate
P92x/EN CM/I52 Techncal Guide Commissioning Guide Page 20/26 MiCOM P921/P922 & P923
Stage (f1>) check:
1. If time delay (tf1>) is short, gradually increase the frequency from the nominal frequency fn to the value of the stage (f1>): tripping should occur for a frequency in the range [(f1>) – 10mHz, (f1>) + 10mHz].

5.5.3 Test example: stage df/dt1 & df/dt2
First program the first stage of df/dt at +0.5 Hz/s and the second stage at –0.5 Hz/s.
NOTE: the setting of the Δt should be low as mush as it is possible than the period in order to detect the small variation within the time.
Select for example a range of frequency from 50 Hz to 51 Hz with a variation of 1 mHz every 1 ms. The result is shown in the table (1st line). If you assign the 1st threshold to the tripping relay (RL1), so tripping will occur.
Repeat the test with a range of (50 – 49 Hz), now the 2nd threshold will operate.
Also you can assign these threshold to output relays and LEDs and verify the functioning of these elements.

6. ON-LOAD CHECKS - VOLTAGE INPUT CONNECTIONS
The following on-load measuring checks ensure the external wiring to the voltage inputs is correct but can only be carried out if there are no restrictions preventing the energisation of the plant being protected.
REMOVE ALL TEST LEADS, TEMPORARY SHORTING LEADS, ETC. AND REPLACE ANY EXTERNAL WIRING THAT HAS BEEN REMOVED TO ALLOW TESTING.
IF IT HAS BEEN NECESSARY TO DISCONNECT ANY OF THE EXTERNAL WIRING FROM THE RELAY IN ORDER TO PERFORM ANY OF THE FOREGOING TESTS, IT SHOULD BE ENSURED THAT ALL CONNECTIONS ARE REPLACED IN ACCORDANCE WITH THE RELEVANT EXTERNAL CONNECTION OR SCHEME DIAGRAM.
USING A MULTIMETER, MEASURE THE VOLTAGE TRANSFORMER SECONDARY VOLTAGES TO ENSURE THEY ARE CORRECTLY RATED. CHECK THAT THE SYSTEM PHASE ORDER IS CORRECT USING A PHASE METER.
COMPARE THE VALUES OF THE SECONDARY PHASE VOLTAGES WITH THE RELAY'S MEASURED VALUES, WHICH CAN BE FOUND IN THE MEASUREMENTS MENU.
The values measured by the MiCOM relay should be within 1% of the applied primary voltages. However, an additional allowance must be made for the accuracy of the test equipment being used.
Technical Guide P92x/EN CM/I52 Commissioning Guide MiCOM P921/P922 & P923 Page 23/26
7. FINAL CHECKS
The tests are now complete.
REMOVE ALL TEST OR TEMPORARY SHORTING LEADS, ETC. IF IT HAS BEEN NECESSARY TO DISCONNECT ANY OF THE EXTERNAL WIRING FROM THE RELAY IN ORDER TO PERFORM THE WIRING VERIFICATION TESTS, IT SHOULD BE ENSURED THAT ALL CONNECTIONS ARE REPLACED IN ACCORDANCE WITH THE RELEVANT EXTERNAL CONNECTION OR SCHEME DIAGRAM.
If the relay is in a new installation or the circuit breaker has just been maintained, the circuit breaker maintenance counters should be reset to zero. To do this, go to the "CB DATA" menu (P922-P923).
If an MMLG test block is installed, remove the MMLB01 test plug and replace the MMLG cover so that the protection is put into service.
Ensure that all event records (P922-P923), fault records (P922-P923), disturbance records (P922-P923), alarms and LEDs have been reset before leaving the relay.
If applicable, replace the secondary front cover on the relay.
P92x/EN CM/I52 Techncal Guide Commissioning Guide Page 24/26 MiCOM P921/P922 & P923
8. PREVENTATIVE MAINTENANCE
8.1 Maintenance period
It is recommended that products supplied by Schneider Electric receive periodic monitoring after installation. As with all products some deterioration with time is inevitable. In view of the critical nature of protective relays and their infrequent operation, it is desirable to confirm that they are operating correctly at regular intervals.
Schneider Electric protective relays are designed for a life in excess of 20 years.
The MiCOM P921-P922-P923 protection relays are self-checking. They thus require less maintenance than models using earlier technologies. Most problems will result in an alarm so that remedial action can be taken. However, some periodic tests should be done to ensure that the relay is functioning correctly and the external wiring is intact.
If a preventative maintenance policy exists within the customer’s organisation then the recommended product checks should be included in the regular programme. Maintenance periods will depend on many factors, such as:
• the operating environment
• accessibility of the site
• amount of available manpower
• importance of the installation in the power system
• consequences of failure
8.2 Maintenance checks
Although some functionality checks can be performed from a remote location by utilising the communications ability of the relays, these are predominantly restricted to checking that the relay is measuring the applied voltages accurately, and checking the circuit breaker maintenance counters. Therefore it is recommended that maintenance checks are performed locally (i.e. at the substation itself).
Before carrying out any work on the equipment the user should be familiar with the contents of the Safety Section/Safety Guide SFTY/4LM/D11 or later issue and the ratings on the equipment’s rating label.
8.2.1 Alarms
The alarm status LED should first be checked to identify if any alarm conditions exist. If so, press the read key repeatedly to display the alarms individually. Clear the alarms (key ) to extinguish the LED.
8.2.2 Opto-isolated inputs
The opto-isolated inputs can be checked to ensure that the relay responds to their energisation by repeating the commissioning test detailed in Section 4.2.4 of this chapter.
8.2.3 Output relays
The output relays can be checked to ensure that they operate by repeating the commissioning test detailed in Section 4.2.5 of this chapter.
Technical Guide P92x/EN CM/I52 Commissioning Guide MiCOM P921/P922 & P923 Page 25/26
8.2.4 Measurement accuracy
If the power system is energised, the values measured by the relay can be compared with known system values to check that they are in the approximate range expected. If they are then the analogue/digital conversion and calculations are being performed correctly by the relay. Suitable test methods can be found in Section 6 of this chapter.
Alternatively, the values measured by the relay can be checked against known values injected into the relay via the test block, if fitted, or injected directly into the relay terminals. Suitable test methods can be found in Section 7 of this chapter. These tests will prove the calibration accuracy is being maintained.
8.3 Method of repair
If the relay should develop a fault while energised, depending on the nature of the fault, the watchdog contacts will change state and an alarm will be generated. Due to the use of surface-mount components, faulty PCBs should be replaced as it is not possible to perform repairs on damaged circuits. Thus either the complete relay or just the faulty PCB, identified by the relay’s diagnostic software, can be replaced. Refer to Chapter P92x/EN FT of this Technical Guide for more information on alarms.
The preferred method is to replace the complete relay as it ensures that the internal circuitry is protected against electrostatic discharge and physical damage at all times and overcomes the possibility of incompatibility between replacement PCBs. However, it may be difficult to remove an installed relay due to limited access in the back of the cubicle and rigidity of the scheme wiring: to avoid such difficulties, the MiCOM P921-P922-P923 relays are designed to be removed while energised for fast replacement of the live part of the relay, thus minimising the absence of protection.
BEFORE CARRYING OUT ANY WORK ON THE EQUIPMENT THE USER SHOULD BE FAMILIAR WITH THE CONTENTS OF THE SAFETY SECTION/SAFETY GUIDE SFTY/4LM/D11 OR LATER ISSUE AND THE RATINGS ON THE EQUIPMENT’S RATING LABEL. THIS SHOULD ENSURE THAT NO DAMAGE IS CAUSED BY INCORRECT HANDLING OF THE ELECTRONIC COMPONENTS.
8.3.1 Replacing the complete relay
The MiCOM P921-P922-P923 relays can be removed and replaced if necessary without having to disconnect the rear terminals.
This is possible while the relay is energised. It is however recommended that all auxiliary supplies are isolated before working on the relay.
P92x/EN CM/I52 Techncal Guide Commissioning Guide Page 26/26 MiCOM P921/P922 & P923
8.4 Changing the battery (for Phase 1 only)
Each relay Phase 1 has a battery to maintain records (P922-P923) and the correct time in case the auxiliary supply fails. The data maintained in a P922-P923 relay thus includes event, fault and disturbance records at the time of failure.
This battery will periodically need changing, although an alarm will be given as part of the relay's periodic self-monitoring in the event of a low battery condition.
8.4.1 Instructions for replacing the battery
Open the bottom cover on the front of the relay.
Gently extract the battery from its socket. If necessary, use a small screwdriver to prize the battery free.
Ensure that the metal terminals in the battery socket are free from corrosion, grease and dust.
The replacement battery should be removed from its packaging and placed into the battery holder, taking care to ensure that the polarity markings on the battery agree with those adjacent to the socket.
NOTE: Only use a type ½AA lithium battery with a nominal voltage of 3.7V.
Ensure that the battery is securely held in its socket and that the battery terminals are making good contact with the metal terminals of the socket.
Close the bottom cover on the front of the relay.
8.4.2 Post modification tests
To ensure that the replacement battery will maintain the date and time if the auxiliary supply fails, change the date and time on the relay, then disconnect and reconnect the auxiliary supply. The date and time should be maintained.
8.4.3 Battery disposal
The battery that has been removed should be disposed of in accordance with the disposal procedure for Lithium batteries in the country in which the relay is installed.
8.5 Cleaning
Before cleaning the equipment ensure that all inputs (auxiliary supply, current, voltage) are isolated to prevent any risk of electric shock.
The equipment may be cleaned using a clean, damp cloth. Do not use detergents, solvents or abrasive cleaners as they may damage the relay's surface and leave a conductive residue.
